Title: Pyridinyl derivatives as sodium channel activators

Description:
TECHNICAL FIELD 
     This disclosure is directed to pyridinyl derivatives, as stereoisomers, enantiomers, or tautomers thereof or mixtures thereof; or pharmaceutically acceptable salts, solvates, or prodrugs thereof, and pharmaceutical compositions comprising the pyridinyl derivatives, which are useful as voltage-gated sodium channel activators and are therefore are useful in treating seizure disorders such as epilepsy. 
     BACKGROUND 
     Epilepsy is a common seizure disorder, with a worldwide estimated prevalence of 0.7% of the population (50 million people) (see Hirtz, D. et al.,  Neurology . (2007), 68:326-337). It is characterized by abnormal electrical activities in the brain leading to seizures. For epidemiological purposes, the definition requires more than one unprovoked seizure of any type. 
     Patients with epilepsy have an increased mortality risk compared with the general population due primarily to the etiology of the disease. However, in patients with uncontrolled epilepsy, the greatest seizure-related risk of mortality is due to sudden unexpected death in epilepsy (SUDEP) (see, Hitiris, N. et al.,  Epilepsy and Behavior  (2007), 10:363-376. Patients who participate in clinical trials of investigational antiepileptic drugs (AEDs) generally have had epilepsy for more than 10 years and have failed multiple AED therapies. 
     The pathophysiology of most forms of epilepsy remains poorly understood, but it is known that epileptic seizures arise from an excessively synchronous and sustained firing of a group of neurons. Persistent increase in neuronal excitability is common to all epileptic syndromes. The therapeutic strategy in treating epilepsy involves reducing neuronal excitability through various mechanistic pathways. Over the past two decades, several new AEDs were developed and marketed to expand the therapeutic spectrum by targeting different mechanisms of action and to improve the risk/benefit profile. Currently available AEDs are considered to act by inhibition of synaptic vesicle glycoprotein, potentiation of the inhibitory GABAergic neurotransmission, reduction of glutamate-mediated excitatory neurotransmission, or inhibition of voltage-gated sodium or calcium channels. Despite this, up to 30% of patients remain refractory to conventional treatment and continue to have uncontrolled seizures (see Brown, D. A. et al.,  Nature  (1980), 283:673-676, and Elger, C. E. et al.,  Epilepsy Behav . (2008), 12:501-539. The quality of life in refractory patients is poor; they cannot drive a car, and they have difficulty working or living independently. Additionally, many patients have behavioral, neurological, and/or intellectual disturbances as sequelae of their seizure disorder. Current agents have minimal to no effects on neuronal sodium-gated channels, in spite of the fact that these channels have a major role in the control of neuronal excitability. Medicines with novel mechanisms of action, or medicines that improve on the already marketed AEDs are therefore needed to address the significant unmet clinical need for seizure control in patients with treatment-resistant epilepsy. 
     Na v 1.1 is a voltage-gated sodium channel (Na v ), comprising one pore-forming α-subunit encoded by SCN1A and two associated β-subunits encoded by SCN1B-SCN4B. Na v 1.1 as well as its subfamilies (Na v 1.2, Na v 1.3 and Na v 1.6), is predominantly expressed in the central nervous system (CNS) (Catterall, W. A.,  J Physiol  (2012), Vol. 590, pp. 2577-2589, and Catterall, W. A.,  Neurochem Res  (2017), Vol. 42, pp. 2495-2504). Na v 1.1 is largely expressed in parvalbuminpositive fast spiking interneurons (FSINs) and is involved in membrane depolarization and action potential (AP) firing (Ogiwara, I. et al.,  J Neurosci  (2007), Vol. 27, pp. 5903-5914). Therefore, loss of function of the Na v 1.1 channels could lead to disinhibition of excitatory pyramidal neurons causing various diseases of the CNS (Han, S. et al.,  Nature  (2012), Vol. 489, pp. 385-390, Oakley, J. C. et al.  Epilepsia  (2011), Vol. 52 (Suppl. 2), pp. 59-61, and Verret, L. et al.,  Cell  (2012), Vol. 149, pp. 708-721). Dravet syndrome is a rare genetic epileptic encephalopathy, where more than 70% of patients have de novo heterozygous mutations of the SCN1A gene (Catterall, W. A.,  Ann Rev Pharmacol Toxicol  (2014), Vol. 54, pp. 317-338). In these mutations, a loss of function of the Na v 1.1 channels has been reported (Mantegazza, M. et al.,  Proc Natl Acad Sci USA  (2005), Vol. 102, pp. 18177-18182). The genetic link between Dravet syndrome patients and Na v 1.1 channels suggest that a brain penetrant Na v 1.1 activator could possess significant therapeutic potential for treating Dravet syndrome (Jensen, H. S. et al.,  Trends Pharmacol Sci  (2014), Vol. 35, pp. 113-118, and Richards, K. L. et al.,  Proc Natl Acad Sci USA  (2018), Vol. 115, pp. E8077-E8085). However, potent and selective Na v 1.1 activators have not been reported to date. Recently, a few Na v 1.1 activators have been reported by Lundbeck: a 2-methylbenzamide derivative (Crestey, F. et al.,  ACS Chem Neurosci  (2015), Vol. 6, pp. 1302-1308), AA43279 (Frederiksen, K. et al.,  Eur J Neurosci  (2017), Vol. 46, pp. 1887-1896) and Lu AE98134 (von Schoubyea, N. L. et al.,  Neurosci Lett  (2018), Vol. 662, pp. 29-35). The most recently developed activator, Lu AE98134, increases the total area under the curve for the duration of the depolarizing pulse from 1 μM in Na v 1.1-expressing HEK cells, while issues of low selectivity against Na v 1.5 and moderate selectivity against Na v 1.2 were observed. Biologically, Na v 1.5 is a major cardiac sodium channel (Vincent, G. M.,  Annu Rev Med  (1998), Vol. 49, pp. 263-274) and Na v 1.2 is dominantly expressed in excitatory neurons (Gong, B. et al.,  J Comp Neurol  (1999), Vol. 412, pp. 342-352, and Hu, W. et al.,  Nat Neurosci  (2009), Vol. 12, pp. 996-1002). Therefore, high selectivity against Na v 1.5 and Na v 1.2 is preferable for drug candidates. On the other hand, the electrophysiology data regarding Lu AE98134 reveals promising potency as a Na v 1.1 activator for increasing the excitability of FSINs. The discovery of a 4-phenyl-2-(pyrrolidinyl)nicotinamide derivative as a highly potent Na v 1.1 activator with improved selectivity against Na v 1.2 and Na v 1.5 compared with previously reported Na v 1.1 activators was recently published (Miyazaki, T. et al.,  Bioorg Med Chem Lett  (2019), Vo. 29, No. 6, pp. 815-820). 
     While significant advances have been made in this field, there remains a substantial need for compounds which are voltage-gated sodium channel activators, thereby being useful in treating seizure disorders, preferably epilepsy, in a mammal, preferably a human.

     “Prodrugs” is meant to indicate a compound that may be converted under physiological conditions or by solvolysis to a biologically active compound of the disclosure. Thus, the term “prodrug” refers to a metabolic precursor of a compound of the disclosure that is pharmaceutically acceptable. A prodrug may be inactive when administered to a subject in need thereof, but is converted in vivo to an active compound of the disclosure. Prodrugs are typically rapidly transformed in vivo to yield the parent compound of the disclosure, for example, by hydrolysis in blood. The prodrug compound often offers advantages of solubility, tissue compatibility or delayed release in a mammalian organism (see, Bundgard, H.,  Design of Prodrugs  (1985), pp. 7-9, 21-24 (Elsevier, Amsterdam)). A discussion of prodrugs is provided in Higuchi, T., et al., “Pro-drugs as Novel Delivery Systems,” A.C.S. Symposium Series, Vol. 14, and in Bioreversible Carriers in Drug Design, Ed. Edward B. Roche, American Pharmaceutical Association and Pergamon Press, 1987, both of which are incorporated in full by reference herein. 
     The term “prodrug” is also meant to include any covalently bonded carriers, which release the active compound of the disclosure in vivo when such prodrug is administered to a mammalian subject. Prodrugs of a compound of the disclosure may be prepared by modifying functional groups present in the compound of the disclosure in such a way that the modifications are cleaved, either in routine manipulation or in vivo, to the parent compound of the disclosure. Prodrugs include compounds of the disclosure wherein a hydroxy, amino or mercapto group is bonded to any group that, when the prodrug of the compound of the disclosure is administered to a mammalian subject, cleaves to form a free hydroxy, free amino or free mercapto group, respectively. Examples of prodrugs include, but are not limited to, acetate, formate and benzoate derivatives of alcohol or amide derivatives of amine functional groups in the compounds of the disclosure and the like. 
     “Stable compound” and “stable structure” are meant to indicate a compound that is sufficiently robust to survive isolation to a useful degree of purity from a reaction mixture, and formulation into an efficacious therapeutic agent. 
     “Mammal” includes humans and both domestic animals such as laboratory animals and household pets, (e.g., cats, dogs, swine, cattle, sheep, goats, horses, rabbits), and non-domestic animals such as wildelife and the like. 
     “Optional” or “optionally” means that the subsequently described event of circumstances may or may not occur, and that the description includes instances where said event or circumstance occurs and instances in which it does not. For example, “optionally substituted aryl” means that the aryl radical may or may not be substituted and that the description includes both substituted aryl radicals and aryl radicals having no substitution (“unsubstituted). When a functional group is described as “optionally substituted,” and in turn, substituents on the functional group are also “optionally substituted” and so on, for the purposes of this disclosure, such iterations are limited to five, preferably such iterations are limited to two. 
     “Pharmaceutically acceptable carrier, diluent or excipient” includes without limitation any adjuvant, carrier, excipient, glidant, sweetening agent, diluent, preservative, dye/colorant, flavor enhancer, surfactant, wetting agent, dispersing agent, suspending agent, stabilizer, isotonic agent, solvent, or emulsifier which has been approved by the United States Food and Drug Administration as being acceptable for use in humans or domestic animals. 
     “Pharmaceutically acceptable salt” includes both acid and base addition salts. 
     “Pharmaceutically acceptable acid addition salt” refers to those salts which retain the biological effectiveness and properties of the free bases, which are not biologically or otherwise undesirable, and which are formed with inorganic acids such as, but are not limited to, hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid and the like, and organic acids such as, but not limited to, acetic acid, 2,2-dichloroacetic acid, adipic acid, alginic acid, ascorbic acid, aspartic acid, benzenesulfonic acid, benzoic acid, 4-acetamidobenzoic acid, camphoric acid, camphor-10-sulfonic acid, capric acid, caproic acid, caprylic acid, carbonic acid, cinnamic acid, citric acid, cyclamic acid, dodecylsulfuric acid, ethane-1,2-disulfonic acid, ethanesulfonic acid, 2-hydroxyethanesulfonic acid, formic acid, fumaric acid, galactaric acid, gentisic acid, glucoheptonic acid, gluconic acid, glucuronic acid, glutamic acid, glutaric acid, 2-oxo-glutaric acid, glycerophosphoric acid, glycolic acid, hippuric acid, isobutyric acid, lactic acid, lactobionic acid, lauric acid, maleic acid, malic acid, malonic acid, mandelic acid, methanesulfonic acid, mucic acid, naphthalene-1,5-disulfonic acid, naphthalene-2-sulfonic acid, 1-hydroxy-2-naphthoic acid, nicotinic acid, oleic acid, orotic acid, oxalic acid, palmitic acid, pamoic acid, propionic acid, pyroglutamic acid, pyruvic acid, salicylic acid, 4-aminosalicylic acid, sebacic acid, stearic acid, succinic acid, tartaric acid, thiocyanic acid, p-toluenesulfonic acid, trifluoroacetic acid, undecylenic acid, and the like. 
     “Pharmaceutically acceptable base addition salt” refers to those salts which retain the biological effectiveness and properties of the free acids, which are not biologically or otherwise undesirable. These salts are prepared from addition of an inorganic base or an organic base to the free acid. Salts derived from inorganic bases include, but are not limited to, the sodium, potassium, lithium, ammonium, calcium, magnesium, iron, zinc, copper, manganese, aluminum salts and the like. Preferred inorganic salts are the ammonium, sodium, potassium, calcium, and magnesium salts.

Particularly preferred organic bases are isopropylamine, diethylamine, ethanolamine, trimethylamine, dicyclohexylamine, choline and caffeine. 
     Often crystallizations produce a solvate of the compound of the disclosure. As used herein, the term “solvate” refers to an aggregate or solid form that comprises one or more molecules of a compound of the disclosure with one or more molecules of solvent. The solvent may be water, in which case the solvate may be a hydrate. Alternatively, the solvent may be an organic solvent. Thus, the compounds of the present disclosure may exist as a hydrate, including a monohydrate, dihydrate, hemihydrate, sesquihydrate, trihydrate, tetrahydrate and the like, as well as the corresponding solvated forms. The compound of the disclosure may be true solvates, while in other cases; the compound of the disclosure may merely retain adventitious water or be a mixture of water plus some adventitious solvent. 
     A “pharmaceutical composition” refers to a formulation of a compound of the disclosure and a medium generally accepted in the art for the delivery of the biologically active compound to mammals, e.g., humans. Such a medium includes all pharmaceutically acceptable carriers, diluents or excipients therefor. 
     “Seizure disorders” refers to seizures and disorders associated with seizures such as partial onset (focal) seizures, photosensitive epilepsy, self-induced syncope, intractable epilepsy, Angelman syndrome, benign rolandic epilepsy, CDKL5 disorder, childhood and juvenile absence epilepsy, Dravet syndrome, frontal lobe epilepsy, Glut1 deficiency syndrome, hypothalamic hamartoma, infantile spasms/West&#39;s syndrome, juvenile myoclonic epilepsy, Landau-Kleffner syndrome, Lennox-Gastaut syndrome (LGS), epilepsy with myoclonic-absences, Ohtahara syndrome, Panayiotopoulos syndrome, PCDH19 epilepsy, progressive myoclonic epilepsies, Rasmussen&#39;s syndrome, ring chromosome 20 syndrome, reflex epilepsies, temporal lobe epilepsy, Lafora progressive myoclonus epilepsy, neurocutaneous syndromes, tuberous sclerosis complex, early infantile epileptic encephalopathy, early onset epileptic encephalopathy, generalized epilepsy with febrile seizures +, Rett syndrome, multiple sclerosis, Alzheimer&#39;s disease, autism, ataxia, hypotonia and paroxysmal dyskinesia. Preferably, the term “seizure disorder” refers to partial onset (focal) epilepsy. 
     “Therapeutically effective amount” refers to a range of amounts of a compound of the disclosure, which, upon administration to a human, treats, ameliorates or prevents a seizure disorder, preferably epilepsy, in the human, or exhibits a detectable therapeutic or preventative effect in the human having a seizure disorder. The effect is detected by, for example, a reduction in seizures (frequency) or by the severity of seizures (quality). The precise therapeutically effective amount for a given human will depend upon the human&#39;s size and health, the nature and extent of the seizure disorder, the presence of any concomitant medications, and other variables known to those of skill in the art. The therapeutically effective amount for a given situation is determined by routine experimentation and is within the judgment of the clinician. 
     “Treatment” refers to therapeutic applications to slow or stop progression of a seizure disorder, prophylactic application to prevent development of a seizure disorder, and/or reversal of a seizure disorder. Reversal of a seizure disorder differs from a therapeutic application which slows or stops a seizure disorder in that with a method of reversing, not only is progression of a seizure disorder completely stopped, cellular behavior is moved to some degree toward a normal state that would be observed in the absence of the seizure disorder. 
     “Treating” or “treatment” as used herein covers the treatment of the disease or condition of interest in a mammal, preferably a human, having the disease or condition of interest, and includes: 
     (a) preventing the disease or condition from occurring in a mammal, in particular, when such mammal is predisposed to the condition but has not yet been diagnosed as having it; 
     (b) inhibiting the disease or condition, i.e., arresting its development; 
     (c) relieving (or ameliorating) the disease or condition, i.e., causing regression of the disease or condition; or 
     (d) relieving (or ameliorating) the symptoms resulting from the disease or condition, i.e., relieving a seizure disorder without addressing the underlying disease or condition. 
     As used herein, the terms “disease” and “condition” may be used interchangeably or may be different in that the particular malady or condition may not have a known causative agent (so that etiology has not yet been worked out) and it is therefore not yet recognized as a disease but only as an undesirable condition or syndrome, wherein a more or less specific set of symptoms have been identified by clinicians. 
     The compounds of this disclosure may contain at least one asymmetric carbon atom and thus may exist as racemates, enantiomers, and/or diastereoisomers. For the present disclosure, the words diastereomer and diastereoisomer and related terms are equivalent and interchangeable. Unless otherwise indicated, this disclosure includes all enantiomeric and diastereoisomeric forms of the compounds of formula (I). Pure stereoisomers, mixtures of enantiomers and/or diastereoisomers, and mixtures of different compounds of the disclosure are included herein. Thus, compounds of formula (I) or (II) may occur as racemates, racemic or diastereoisomeric mixtures and as individual diastereoisomers, or enantiomers, unless a specific stereoisomer enantiomer or diastereoisomer is identified, with all isomeric forms being included in the present disclosure. For this disclosure, a racemate or racemic mixture implies a 50:50 mixture of stereoisomers only. Other enantiomerically or diastereomerically enriched mixtures of varying ratios of stereoisomers are also contemplated. 
     “Enantiomers” refer to asymmetric molecules that can exist in two different isomeric forms which have different configurations in space. Other terms used to designate or refer to enantiomers include “stereoisomers” (because of the different arrangement or stereochemistry around the chiral center; although all enantiomers are stereoisomers, not all stereoisomers are enantiomers) or “optical isomers” (because of the optical activity of pure enantiomers, which is the ability of different pure enantiomers to rotate plane-polarized light in different directions). Because they do not have a plane of symmetry, enantiomers are not identical with their mirror images; molecules which exist in two enantiomeric forms are chiral, which means that they can be regarded as occurring in “left” and “right” handed forms. The most common cause of chirality in organic molecules is the presence of a tetrahedral carbon bonded to four different substituents or groups. Such a carbon is referred to as a chiral center, or stereogenic center. 
     Enantiomers have the same empirical chemical formula, and are generally chemically identical in their reactions, their physical properties, and their spectroscopic properties. However, enantiomers show different chemical reactivity toward other asymmetric compounds, and respond differently toward asymmetric physical disturbances. The most common asymmetric disturbance is polarized light. 
     An enantiomer can rotate plane-polarized light; thus, an enantiomer is optically active. Two different enantiomers of the same compound will rotate plane-polarized light in the opposite direction; thus, the light can be rotated to the left or counterclockwise for a hypothetical observer (this is levarotatory or “I”, or minus or “−”) or it can be rotated to the right or clockwise (this is dextrorotatory or “d” or plus or “+”). The sign of optical rotation (+) or (−), is not related to the R,S designation. A mixture of equal amounts of two chiral enantiomers is called a racemic mixture, or racemate, and is denoted either by the symbol (+/−) or by the prefix “d,l” to indicate a mixture of dextrorotatory and levorotatory forms. Racemates or racemic mixtures show zero optical rotation because equal amounts of the (+) and (−) forms are present. In general, the presence of a single enantiomer rotates polarized light in only one direction; thus, a single enantiomer is referred to as optically pure. 
     The designations “R” and “S” are used to denote the three-dimensional arrangement of atoms (or the configuration) of the stereogenic center. The designations may appear as a prefix or as a suffix; they may or may not be separated from the enantiomer name by a hyphen; they may or may not be hyphenated; and they may or may not be surrounded by parentheses. A method for determining the designation is to refer to the arrangement of the priority of the groups at the stereogenic center when the lowest priority group is oriented away from a hypothetical observer: If the arrangement of the remaining three groups from the higher to the lower priority is clockwise, the stereogenic center has an “R” configuration; if the arrangement is counterclockwise, the stereogenic center has an “S” configuration. 
     “Resolution” or “resolving” when used in reference to a racemic compound or mixture refers to the separation of a racemate into its two enantiomeric forms (i.e., (+) and (−); (R) and (S) forms). 
     “Enantiomeric excess” or “ee” refers to a product wherein one enantiomer is present in excess of the other, and is defined as the absolute difference in the mole fraction of each enantiomer. Enantiomeric excess is typically expressed as a percentage of an enantiomer present in a mixture relative to the other enantiomer. For purposes of this disclosure, the (S)-enantiomer of a compound prepared by the methods disclosed herein is considered to be “substantially free” of the corresponding (R)-enantiomer when the (S)-enantiomer is present in enantiomeric excess of greater than 80%, preferably greater than 90%, more preferably greater than 95% and most preferably greater than 99%. 
     Certain compounds have been labeled with “P1”, “P2”, et seq. or “D1”, “D2”, et seq. This demarcation indicates a compound is a first eluting peak (i.e., P1) from a chiral separation technique and does not necessarily indicate a specific stereochemistry. 
     A “tautomer” refers to a proton shift from one atom of a molecule to another atom of the same molecule. The present disclosure includes tautomers of any compound of formula (I) or (II) as described herein. 
     “Isotopologue” refers to a collection of molecules having an identical chemical structure, except that there may be isotopic variation among the constituent atoms of the molecules. Thus, it will be clear to those of skill in the art that a compound represented by a particular chemical structure containing indicated deuterium atoms, will also contain lesser amounts of isotopologues having hydrogen atoms at one or more of the designated deuterium positions in that structure. The relative amount of such isotopologues in a compound will depend upon a number of factors including the isotopic purity of deuterated reagents used to make the compound and the efficiency of incorporation of deuterium in the various synthesis steps used to prepare the compound. The relative amount of such isotopologues in toto will be less than 49.9% of the compound. In other embodiments, the relative amount of such isotopologues in toto will be less than 47.5%, less than 40%, less than 32.5%, less than 25%, less than 17.5%, less than 10%, less than 5%, less than 3%, less than 1%, or less than 0.5% of the compound. 
     The use of parentheses and brackets in substituent groups may be used herein to conserve space. Accordingly, the use of parenthesis in a substituent group indicates that the group enclosed within the parentheses is attached directly to the atom preceding the parenthesis. The use of brackets in a substituent group indicates that the group enclosed within the brackets is also attached directly to the atom preceding the parenthesis. 
     For example, a compound of formula (I) or (II) wherein a compound having the following structure: 
     
       
         
         
             
             
         
       
     
     is named herein as (S)-6-chloro-N-(4-(2,5-difluorophenyl)-2-(3-fluoropyrrolidin-1-yl)pyridin-3-yl)nicotinamide.

     The present disclosure readily affords many different means for identification of sodium channel modulating agents that are useful as therapeutic agents. Identification of modulators of sodium channels can be assessed using a variety of in vitro and in vivo assays, e.g., measuring current, measuring membrane potential, measuring ion flux, (e.g., sodium), measuring sodium concentration, measuring second messengers and transcription levels, measuring neurotransmitter levels and using voltage-sensitive dyes, radioactive tracers, multi-electrode-arrays and patch-clamp electrophysiology. 
     One such protocol involves the screening of chemical agents for ability to modulate the activity of a sodium channel thereby identifying it as a modulating agent. 
     A typical assay described in (Crestey, F. et al.,  ACS Chem Neurosci  (2015), Vol. 6, pp. 1302-1308), AA43279 (Frederiksen, K. et al.,  Eur J Neurosci  (2017), Vol. 46, pp. 1887-1896) and Lu AE98134 (von Schoubyea, N. L. et al.,  Neurosci Lett  (2018), Vol. 662, pp. 29-35) employs the use of automated planar patch clamp techniques to study the effects of the chemical agent on the gating of sodium channels. The sodium channel isoforms of interest are stably expressed in Human Embryonic Kidney Cells and the currents that flow through those channels in response to a depolarizing voltage clamp step from −120 mV to 0 mV are measured in the presence of increasing concentrations of the chemical agents. The area under the sodium current trace which correlates to the magnitude of sodium flux through the cell membrane is used to quantify the effects on gating of the channels. Other parameters that are measured in the assay include the peak current, time constant of open state inactivation and the voltage dependence of steady state inactivation properties. The concentration responses are used to determine potency of each chemical agents effects on modulating the sodium channel isoform gating. Such techniques are known to those skilled in the art, and may be developed, using current technologies, into low or medium throughput assays for evaluating compounds for their ability to modulate sodium channel behaviour. 
     The results of these assays provide the basis for analysis of the structure-activity relationship (SAR) between compounds of the disclosure and the sodium channel. Certain substituents on the core structure of a compound of the disclosure tend to provide more potent inhibitory or potentiating compounds. SAR analysis is one of the tools those skilled in the art may now employ to identify preferred embodiments of the compounds of the disclosure for use as therapeutic agents. 
     In an alternative use of the disclosure, the compounds of the disclosure can be used in in vitro or in vivo studies as exemplary agents for comparative purposes to find other compounds also useful in treatment of, or protection from, the various diseases disclosed herein. 
     In another embodiment, the compounds of formula (I) or (II), as individual stereoisomers, enantiomers, or tautomers thereof or mixtures thereof; or pharmaceutically acceptable salts, solvates, or prodrugs thereof, as set forth above in the Brief Summary, as stereoisomers, enantiomers, tautomers thereof or mixtures thereof, or pharmaceutically acceptable salts, solvates, or prodrugs thereof, and/or the pharmaceutical compositions described herein which comprise a pharmaceutically acceptable excipient and one or more compounds of the disclosure, as set forth above in the Brief Summary, as a stereoisomer, enantiomer, or tautomer thereof or mixtures thereof, or a pharmaceutically acceptable salt, solvate, or prodrug thereof, can be used in the preparation of a medicament for the treatment of a sodium channel-mediated disease or condition in a mammal. 
     Pharmaceutical Compositions and Administration 
     This disclosure is also directed to pharmaceutical compositions containing the compounds of formula (I) or (II), as described above in the Brief Summary, as stereoisomers, enantiomers, or tautomers thereof or mixtures thereof; or pharmaceutically acceptable salts, solvates, or prodrugs thereof. In one embodiment, the present disclosure relates to a pharmaceutical composition comprising compounds of formula (I) or (II), as described above in the Brief Summary, as stereoisomers, enantiomers, or tautomers thereof or mixtures thereof; or pharmaceutically acceptable salts, solvates, or prodrugs thereof, in a pharmaceutically acceptable carrier, excipient or diluent and in an amount effective to modulate, preferably inhibit, voltage-gated sodium channels to treat certain diseases or conditions, such as epilepsy, when administered to an animal, preferably a mammal, most preferably a human patient. 
     Administration of the compounds of formula (I) or (II), as described above in the Brief Summary, as stereoisomers, enantiomers, or tautomers thereof or mixtures thereof; or pharmaceutically acceptable salts, solvates, or prodrugs thereof, in pure form or in an appropriate pharmaceutical composition, can be carried out via any of the accepted modes of administration of agents for serving similar utilities. The pharmaceutical compositions of the disclosure can be prepared by combining a compound of the disclosure with an appropriate pharmaceutically acceptable carrier, diluent or excipient, and may be formulated into preparations in solid, semi-solid, liquid or gaseous forms, such as tablets, capsules, powders, granules, ointments, solutions, suppositories, injections, inhalants, gels, microspheres, and aerosols. Typical routes of administering such pharmaceutical compositions include, without limitation, oral, topical, transdermal, inhalation, parenteral, sublingual, rectal, vaginal, and intranasal. The term “parenteral” as used herein includes subcutaneous injections, intravenous, intramuscular, intrathecal, intrasternal injection or infusion techniques. Pharmaceutical compositions of the disclosure are formulated so as to allow the active ingredients contained therein to be bioavailable upon administration of the composition to a patient. Compositions that will be administered to a subject or patient take the form of one or more dosage units, where for example, a tablet may be a single dosage unit, and a container of a compound of the disclosure in aerosol form may hold a plurality of dosage units. Actual methods of preparing such dosage forms are known, or will be apparent, to those skilled in this art; for example, see  The Science and Practice of Pharmacy,  20th Edition (Philadelphia College of Pharmacy and Science, 2000). The composition to be administered will, in any event, contain a therapeutically effective amount of a compound of the disclosure, or a pharmaceutically acceptable salt thereof, for treatment of a disease or condition of interest in accordance with the teachings of this disclosure. 
     The pharmaceutical compositions useful herein also contain a pharmaceutically acceptable carrier, including any suitable diluent or excipient, which includes any pharmaceutical agent that does not itself induce the production of antibodies harmful to the individual receiving the composition, and which may be administered without undue toxicity. Pharmaceutically acceptable carriers include, but are not limited to, liquids, such as water, saline, glycerol and ethanol, and the like. A thorough discussion of pharmaceutically acceptable carriers, diluents, and other excipients is presented in REMINGTON&#39;S PHARMACEUTICAL SCIENCES (Mack Pub. Co., N.J. current edition). 
     A pharmaceutical composition of the disclosure may be in the form of a solid or liquid. In one aspect, the carrier(s) are particulate, so that the compositions are, for example, in tablet or powder form. The carrier(s) may be liquid, with the compositions being, for example, an oral syrup, injectable liquid, or an aerosol, which is useful in, for example, inhalatory administration. 
     When intended for oral administration, the pharmaceutical composition is preferably in either solid or liquid form, where semi-solid, semi-liquid, suspension and gel forms are included within the forms considered herein as either solid or liquid. 
     As a solid composition for oral administration, the pharmaceutical composition may be formulated into a powder, granule, compressed tablet, pill, capsule, chewing gum, wafer or the like form. Such a solid composition will typically contain one or more inert diluents or edible carriers. In addition, one or more of the following may be present: binders such as carboxymethylcellulose, ethyl cellulose, microcrystalline cellulose, gum tragacanth or gelatin; excipients such as starch, lactose or dextrins, disintegrating agents such as alginic acid, sodium alginate, Primogel, corn starch and the like; lubricants such as magnesium stearate or Sterotex; glidants such as colloidal silicon dioxide; sweetening agents such as sucrose or saccharin; a flavoring agent such as peppermint, methyl salicylate or orange flavoring; and a coloring agent. 
     When the pharmaceutical composition is in the form of a capsule, for example, a gelatin capsule, it may contain, in addition to materials of the above type, a liquid carrier such as polyethylene glycol or oil. 
     The pharmaceutical composition may be in the form of a liquid, for example, an elixir, syrup, solution, emulsion or suspension. The liquid may be for oral administration or for delivery by injection, as two examples. When intended for oral administration, preferred composition contain, in addition to the present compounds, one or more of a sweetening agent, preservatives, dye/colorant and flavor enhancer. In a composition intended to be administered by injection, one or more of a surfactant, preservative, wetting agent, dispersing agent, suspending agent, buffer, stabilizer and isotonic agent may be included. 
     The liquid pharmaceutical compositions of the disclosure, whether they be solutions, suspensions or other like form, may include one or more of the following adjuvants: sterile diluents such as water for injection, saline solution, preferably physiological saline, Ringer&#39;s solution, isotonic sodium chloride, fixed oils such as synthetic mono or diglycerides which may serve as the solvent or suspending medium, polyethylene glycols, glycerin, propylene glycol or other solvents; antibacterial agents such as benzyl alcohol or methyl paraben; antioxidants such as ascorbic acid or sodium bisulfite; chelating agents such as ethylenediaminetetraacetic acid; buffers such as acetates, citrates or phosphates and agents for the adjustment of tonicity such as sodium chloride or dextrose. The parenteral preparation can be enclosed in ampoules, disposable syringes or multiple dose vials made of glass or plastic. Physiological saline is a preferred adjuvant. An injectable pharmaceutical composition is preferably sterile. 
     A liquid pharmaceutical composition of the disclosure intended for either parenteral or oral administration should contain an amount of a compound of the disclosure such that a suitable dosage will be obtained. Typically, this amount is at least 0.01% of a compound of the disclosure in the composition. When intended for oral administration, this amount may be varied to be between 0.1 and about 70% of the weight of the composition. Preferred oral pharmaceutical compositions contain between about 4% and about 50% of the compound of the disclosure. Preferred pharmaceutical compositions and preparations according to the present disclosure are prepared so that a parenteral dosage unit contains between 0.01 to 10% by weight of the compound prior to dilution of the disclosure. 
     The pharmaceutical composition of the disclosure may be intended for topical administration, in which case the carrier may suitably comprise a solution, emulsion, ointment or gel base. The base, for example, may comprise one or more of the following: petrolatum, lanolin, polyethylene glycols, bee wax, mineral oil, diluents such as water and alcohol, and emulsifiers and stabilizers. Thickening agents may be present in a pharmaceutical composition for topical administration. If intended for transdermal administration, the composition may include a transdermal patch or iontophoresis device. Topical formulations may contain a concentration of the compound of the disclosure from about 0.1 to about 10% w/v (weight per unit volume). 
     The pharmaceutical composition of the disclosure may be intended for rectal administration, in the form, for example, of a suppository, which will melt in the rectum and release the drug. The composition for rectal administration may contain an oleaginous base as a suitable nonirritating excipient. Such bases include, without limitation, lanolin, cocoa butter and polyethylene glycol. 
     The pharmaceutical composition of the disclosure may include various materials, which modify the physical form of a solid or liquid dosage unit. For example, the composition may include materials that form a coating shell around the active ingredients. The materials that form the coating shell are typically inert, and may be selected from, for example, sugar, shellac, and other enteric coating agents. Alternatively, the active ingredients may be encased in a gelatin capsule. 
     The pharmaceutical composition of the disclosure in solid or liquid form may include an agent that binds to the compound of the disclosure and thereby assists in the delivery of the compound. Suitable agents that may act in this capacity include a monoclonal or polyclonal antibody, a protein or a liposome. 
     The pharmaceutical composition of the disclosure may consist of dosage units that can be administered as an aerosol. The term aerosol is used to denote a variety of systems ranging from those of colloidal nature to systems consisting of pressurized packages. Delivery may be by a liquefied or compressed gas or by a suitable pump system that dispenses the active ingredients. Aerosols of compounds of the disclosure may be delivered in single phase, bi-phasic, or tri-phasic systems in order to deliver the active ingredient(s). Delivery of the aerosol includes the necessary container, activators, valves, subcontainers, and the like, which together may form a kit. One skilled in the art, without undue experimentation may determine preferred aerosols. 
     The pharmaceutical compositions of the disclosure may be prepared by methodology well known in the pharmaceutical art. For example, a pharmaceutical composition intended to be administered by injection can be prepared by combining a compound of the disclosure with sterile, distilled water so as to form a solution. A surfactant may be added to facilitate the formation of a homogeneous solution or suspension. Surfactants are compounds that non-covalently interact with the compound of the disclosure so as to facilitate dissolution or homogeneous suspension of the compound in the aqueous delivery system. 
     The compounds of the disclosure, or their pharmaceutically acceptable salts, are administered in a therapeutically effective amount, which will vary depending upon a variety of factors including the activity of the specific compound employed; the metabolic stability and length of action of the compound; the age, body weight, general health, sex, and diet of the patient; the mode and time of administration; the rate of excretion; the drug combination; the severity of the particular disorder or condition; and the subject undergoing therapy. Generally, a therapeutically effective daily dose is (for a 70 Kg mammal) from about 0.001 mg/Kg (i.e., 0.07 mg) to about 100 mg/Kg (i.e., 7.0 g); preferably a therapeutically effective dose is (for a 70 Kg mammal) from about 0.01 mg/Kg (i.e., 0.7 mg) to about 50 mg/Kg (i.e., 3.5 g); more preferably a therapeutically effective dose is (for a 70 Kg mammal) from about 1 mg/kg (i.e., 70 mg) to about 25 mg/Kg (i.e., 1.75 g). 
     The ranges of effective doses provided herein are not intended to be limiting and represent preferred dose ranges. However, the most preferred dosage will be tailored to the individual subject, as is understood and determinable by one skilled in the relevant arts. (see, e.g., Berkow et al., eds.,  The Merck Manual,  16 th  edition, Merck and Co., Rahway, N.J., 1992; Goodmanetna., eds.,  Goodman and Cilman&#39;s The Pharmacological Basis of Therapeutics,  10 th  edition, Pergamon Press, Inc., Elmsford, N.Y., (2001);  Avery&#39;s Drug Treatment: Principles and Practice of Clinical Pharmacology and Therapeutics,  3rd edition, ADIS Press,  LTD., Williams and Wilkins , Baltimore, Md. (1987), Ebadi,  Pharmacology , Little, Brown and Co., Boston, (1985); Osolci al., eds.,  Remington&#39;s Pharmaceutical Sciences,  18 th  edition, Mack Publishing Co., Easton, Pa. (1990); Katzung,  Basic and Clinical Pharmacology , Appleton and Lange, Norwalk, Conn. (1992)). 
     The total dose required for each treatment can be administered by multiple doses or in a single dose over the course of the day, if desired. Generally, treatment is initiated with smaller dosages, which are less than the optimum dose of the compound. Thereafter, the dosage is increased by small increments until the optimum effect under the circumstances is reached. The diagnostic pharmaceutical compound or composition can be administered alone or in conjunction with other diagnostics and/or pharmaceuticals directed to the pathology, or directed to other symptoms of the pathology. The recipients of administration of compounds and/or compositions of the disclosure can be any vertebrate animal, such as mammals. Among mammals, the preferred recipients are mammals of the Orders Primate (including humans, apes and monkeys), Arteriodactyla (including horses, goats, cows, sheep, pigs), Rodenta (including mice, rats, rabbits, and hamsters), and Carnivora (including cats, and dogs). Among birds, the preferred recipients are turkeys, chickens and other members of the same order. The most preferred recipients are humans. 
     For topical applications, it is preferred to administer an effective amount of a pharmaceutical composition according to the disclosure to target area, e.g., skin surfaces, mucous membranes, and the like, which are adjacent to peripheral neurons which are to be treated. This amount will generally range from about 0.0001 mg to about 1 g of a compound of the disclosure per application, depending upon the area to be treated, whether the use is diagnostic, prophylactic or therapeutic, the severity of the symptoms, and the nature of the topical vehicle employed. A preferred topical preparation is an ointment, wherein about 0.001 to about 50 mg of active ingredient is used per cc of ointment base. The pharmaceutical composition can be formulated as transdermal compositions or transdermal delivery devices (“patches”). Such compositions include, for example, a backing, active compound reservoir, a control membrane, liner and contact adhesive. Such transdermal patches may be used to provide continuous pulsatile, or on demand delivery of the compounds of the present disclosure as desired. 
     The compositions of the disclosure can be formulated so as to provide quick, sustained or delayed release of the active ingredient after administration to the patient by employing procedures known in the art. Controlled release drug delivery systems include osmotic pump systems and dissolutional systems containing polymer-coated reservoirs or drug-polymer matrix formulations. Examples of controlled release systems are given in U.S. Pat. Nos. 3,845,770 and 4,326,525 and in P. J. Kuzma et al.,  Regional Anesthesia  22 (6): 543-551 (1997), all of which are incorporated herein by reference. 
     The compositions of the disclosure can also be delivered through intra-nasal drug delivery systems for local, systemic, and nose-to-brain medical therapies. Controlled Particle Dispersion (CPD)™ technology, traditional nasal spray bottles, inhalers or nebulizers are known by those skilled in the art to provide effective local and systemic delivery of drugs by targeting the olfactory region and paranasal sinuses. 
     The disclosure also relates to an intravaginal shell or core drug delivery device suitable for administration to the human or animal female. The device may be comprised of the active pharmaceutical ingredient in a polymer matrix, surrounded by a sheath, and capable of releasing the compound in a substantially zero order pattern on a daily basis similar to devises used to apply testosterone as described in PCT Published Patent Application No. WO 98/50016. 
     Current methods for ocular delivery include topical administration (eye drops), subconjunctival injections, periocular injections, intravitreal injections, surgical implants and iontophoresis (uses a small electrical current to transport ionized drugs into and through body tissues). Those skilled in the art would combine the best suited excipients with the compound for safe and effective intra-occular administration. 
     The most suitable route will depend on the nature and severity of the condition being treated. Those skilled in the art are also familiar with determining administration methods (e.g., oral, intravenous, inhalation, sub-cutaneous, rectal etc.), dosage forms, suitable pharmaceutical excipients and other matters relevant to the delivery of the compounds to a subject in need thereof. 
     Combination Therapy 
     The compounds of the disclosure may be usefully combined with one or more other compounds of the disclosure or one or more other therapeutic agent or as any combination thereof, in the treatment of sodium channel-mediated diseases and conditions. For example, a compound of this disclosure may be administered simultaneously, sequentially, or separately in combination with other therapeutic agents, including, but not limited to: 
     Acetazolamide (Diamox), Brivaracetam (Briviact), Cannabidiol (Epidiolex), Carbamazepine (Tegretol), Cenobamate (Xcopri), Clobazam (Frisium), Clonazepam (Klonopin), Eslicarbazepine acetate (Aptiom, Zebinix), Ethosuximide (Zarontin), Felbamate (Felbatol), Fenfluramine (Fintepla), Gabapentin (Neurontin), Lacosamide (Vimpat), Lamotrigine (Lamictal), Levetiracetam (Keppra), Oxcarbazepine (Trileptal), Perampanel (Fycompa), Phenobarbital (Luminal), Phenytoin (Dilantin), Pregabalin (Lyrica), Primidone, Retigabine (Ezogabine), Rufinamide (Banzel), Stiripentol (Diacomit), Sulthiame, Tiagabine (Gabitril), Topiramate (Topamax), Valproate (Depakote), Vigabatrin (Sabril), Zonisamide (Zonegran). 
     As used herein “combination” refers to any mixture or permutation of one or more compounds of the disclosure and one or more other compounds of the disclosure or one 
     or more additional therapeutic agent. Unless the context makes clear otherwise, “combination” may include simultaneous or sequentially delivery of a compound of the disclosure with one or more therapeutic agents. Unless the context makes clear otherwise, “combination” may include dosage forms of a compound of the disclosure with another therapeutic agent. Unless the context makes clear otherwise, “combination” may include routes of administration of a compound of the disclosure with another therapeutic agent. Unless the context makes clear otherwise, “combination” may include formulations of a compound of the disclosure with another therapeutic agent. Dosage forms, routes of administration and pharmaceutical compositions include, but are not limited to, those described herein. 
     Kits-of-Parts 
     The present disclosure also provides kits that contain a pharmaceutical composition which includes one or more compounds of the disclosure. The kit also includes instructions for the use of the pharmaceutical composition for modulating the activity of sodium channels, for the treatment of a seizure disorder, such as epilepsy, as well as other utilities as disclosed herein. Preferably, a commercial package will contain one or more unit doses of the pharmaceutical composition. For example, such a unit dose may be an amount sufficient for the preparation of an intravenous injection. It will be evident to those of ordinary skill in the art that compounds which are light and/or air sensitive may require special packaging and/or formulation. For example, packaging may be used which is opaque to light, and/or sealed from contact with ambient air, and/or formulated with suitable coatings or excipients. 
     Compound Preparation 
     The following Reaction Schemes illustrate methods to make compounds of the disclosure, i.e., compounds of formula (I) or (II), as described above in the Brief Summary, as stereoisomers, enantiomers, or tautomers thereof or mixtures thereof; or pharmaceutically acceptable salts, solvates, or prodrugs thereof. 
     It is also understood that one skilled in the art would be able to make the compounds of the disclosure by similar methods or by methods known to one skilled in the art. It is also understood that one skilled in the art would be able to make in a similar manner as described below other compounds of the disclosure not specifically illustrated below by using the appropriate starting components and modifying the parameters of the synthesis as needed. In general, starting components may be obtained from sources such as Sigma Aldrich, Alfa Aesar, Combi-Blocks, Oakwood Chemicals, Matrix Scientific, and TCI, etc. or synthesized according to sources known to those skilled in the art (see, e.g., M. B. Smith and J. March,  Advanced Organic Chemistry: Reactions , Mechanisms, and Structure, 6th edition (Wiley, 2007)) or prepared as described herein. 
     It is also understood that in the following description, combinations of substituents and/or variables of the depicted formulae are permissible only if such contributions result in stable compounds. 
     It will also be appreciated by those skilled in the art that in the process described below the functional groups of intermediate compounds may need to be protected by suitable protecting groups. Such functional groups include hydroxy, amino, mercapto and carboxylic acid. Suitable protecting groups for hydroxy include trialkylsilyl or diarylalkylsilyl (e.g., t-butyldimethylsilyl, t-butyldiphenylsilyl or trimethylsilyl), tetrahydropyranyl, benzyl, and the like. Suitable protecting groups for amino, include t-butoxycarbonyl, benzyloxycarbonyl, p-methoxybenzyl, trityl and the like. 
     Protecting groups may be added or removed in accordance with standard techniques, which are known to one skilled in the art and as described herein. 
     The use of protecting groups is described in detail in Greene, T. W. and P. G. M. Wuts,  Greene&#39;s Protective Groups in Organic Synthesis  (2006), 4 th  Ed., Wiley. The protecting group may also be a polymer resin such as a Wang resin or a 2-chlorotrityl-chloride resin. 
     It will also be appreciated by those skilled in the art, although such protected derivatives of compounds of this disclosure may not possess pharmacological activity as such, they may be administered to a mammal and thereafter metabolized in the body to form compounds of the disclosure which are pharmacologically active. Such derivatives may therefore be described as “prodrugs”. All prodrugs of compounds of formula (I) or (II) are included within the scope of the disclosure. 
     The compounds of formula (I) or (II) may contain at least one asymmetric carbon atom and thus can exist as racemates, enantiomers, and/or diastereoisomers. Specific enantiomers, or diastereoisomers may be prepared by utilizing the appropriate chiral starting material or through the use of suitable asymmetric synthetic methods. Alternatively, diastereoisomeric mixtures or racemic mixtures of compounds of formula (I) or (II) may be resolved into their respective enantiomers or diastereoisomers. 
     Methods for resolution of diastereoisomeric mixtures or racemic mixtures of the compounds of formula (I) or (II), as described herein, or intermediates prepared herein, are well known in the art (e.g., E. L. Eliel and S. H. Wilen, in  Stereochemistry of Organic Compounds ; John Wiley &amp; Sons: New York, 1994; Chapter 7, and references cited therein). Suitable processes such as crystallization (e.g., preferential crystallization, preferential crystallization in the presence of additives), asymmetric transformation of racemates, chemical separation (e.g., formation and separation of diastereomers such as diastereomeric salt mixtures or the use of other resolving agents; separation via complexes and inclusion compounds), kinetic resolution (e.g., with titanium tartrate catalyst), enzymatic resolution (e.g., lipase mediated) and chromatographic separation (e.g., HPLC with chiral stationary phase and/or with simulated moving bed technology, or supercritical fluid chromatography and related techniques) are some of the examples that may be applied (see e.g., T. J. Ward, Analytical Chemistry, 2002, 2863-2872). 
     In general, compounds of formula (I) or (II), as described above in the Brief Summary, can be synthesized following the general procedure described below in Reaction Schemes 1-13 wherein appropriate starting materials, reagents, substituent groups, coupling partners, protecting groups, etc. are selected to carry out the reactions as shown to arrive at desired compound of formula (I) or (II). 
     For example, in some embodiments, of Reaction Schemes 1-13, R 1  represents 
     
       
         
         
             
             
         
       
     
     R 2  represents 
     
       
         
         
             
             
         
       
     
     PG is a protecting group (e.g., an amine protecting group such as Boc or Fmoc), Z 1  is a halogen (e.g., F, Cl, Br, or I), Z 2  is a halogen (e.g., F, Cl, Br, or I), Z 3  is a suitable coupling partner to Z 1  (e.g., a boronic acid or ester), Z 4  is a suitable coupling partner to Z 2  (e.g., a carboxylic acid, boronic acid or ester), Z 5  is a halogen (e.g., F, Cl, Br, or I), Z 6  is a suitable coupling partner to Z 5  (e.g., a dialkyl amine), Z 7  is a halogen (e.g., F, Cl, Br, or I), and X is oxygen or carbon.

     Step 1. Preparation of 5-nitro-2-((tetrahydrofuran-3-yl)oxy)pyrimidine 
     
       
         
         
             
             
         
       
     
     To a solution of 2-chloro-5-nitro-pyrimidine (0.100 g, 0.627 mmol) and tetrahydrofuran-3-ol (0.110 g, 1.25 mmol) in tetrahydrofuran (2 mL) was added potassium 2-methylpropan-2-olate (1 M in tetrahydrofuran, 0.94 mL) dropwise at 0° C. The mixture was stirred at 20° C. under a nitrogen atmosphere for 12 h. The mixture was poured into saturated aqueous sodium bicarbonate (10 mL) and extracted with ethyl acetate (3×20 mL). The combined organic layers were washed with brine (10 mL), dried over anhydrous sodium sulfate, filtered and the filtrate was evaporated under reduced pressure to afford the title compound as a light yellow oil (0.150 g, crude):  1 H NMR (400 MHz, CDCl 3 ) δ 9.31 (s, 2H), 5.71-5.62 (m, 1H), 4.14-4.09 (m, 1H), 4.07-4.02 (m, 1H), 3.99-3.96 (m, 2H), 2.32-2.20 (m, 2H). 
     Step 2. Preparation of 2-((tetrahydrofuran-3-yl)oxy)pyrimidin-5-amine 
     
       
         
         
             
             
         
       
     
     To a mixture of 5-nitro-2-tetrahydrofuran-3-yloxy-pyrimidine (0.150 g, crude) and ammonium chloride (0.760 g, 1.42 mmol) in ethanol (10 mL) and water (5 mL) was added iron powder (0.198 g, 3.55 mmol) in one portion at 20° C.

To the reaction mixture was added potassium carbonate (0.092 g, 0.67 mmol), 2-(3,4-dihydro-2H-pyran-6-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (0.070 g, 0.34 mmol), [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium(II), complex with CH 2 Cl 2  (1:1) (0.019 g, 0.022 mmol), and the reaction mixture was stirred at 90° C. for 3 h. After cooling to ambient temperature, the mixture was filtered through a bed of Celite, and the filter pad was washed with ethyl acetate (2×20 mL). The filtrate was washed with saturated ammonium chloride (2×25 mL) and concentrated in vacuo. The residue was purified by column chromatography, eluting with a gradient of 10 to 100% of ethyl acetate in heptane, to afford the title compound as a yellow solid (0.070 g, 79% yield): MS (ES+) m/z 389.2 (M+1), 391.2 (M+1).

The reaction mixture was quenched with saturated aqueous sodium bicarbonate solution (10 mL) and extracted with ethyl acetate (3×10 mL). The combined organic extracts were washed with water (3×25 mL) and brine (50 mL), dried over anhydrous sodium sulfate, and concentrated in vacuo. Purification of the residue by preparative reverse phase HPLC, using 5 to 85% of acetonitrile in water containing 0.5% of formic acid as eluent, afforded the title compound as a colorless solid (0.040 g, 45% yield):  1 H-NMR (400 MHz; DMSO-d 6 ) δ 10.34 (s, 1H), 8.97 (s, 2H), 8.61 (d, J=4.9 Hz, 1H), 7.45-7.34 (m, 3H), 7.18-7.14 (m, 1H), 3.20 (7, J=6.9 Hz, 2H), 2.09-1.85 (m, 8H), 1.29 (d, J=6.9 Hz, 6H); MS (ES+) m/z 473.2 (M+1) In a similar manner as described in examples disclosed herein, utilizing the appropriately substituted starting materials and intermediates, the following compounds were prepared:

     To a mixture of 4-(2,5-difluorophenyl)-6-(2-(trifluoromethyl)cyclohexyl)pyrimidin-5-amine (0.11 g, 0.30 mmol) in anhydrous tetrahydrofuran (3.0 mL) was added N,N-diisopropylethylamine (0.31 mL, 1.8 mmol), 2-chloro-1-methylpyridinium iodide (0.23 g, 0.89 mmol) and 2-isopropylpyrimidine-5-carboxylic acid (0.074 g, 0.45 mmol). The reaction mixture was stirred at 65° C. for 8 h. After cooling to ambient temperature, to the reaction mixture was added methanol (3 mL) and 10 M sodium hydroxide (1 mL) and the mixture was stirred at ambient temperature for 10 minutes. The reaction mixture was diluted with ethyl acetate (10 mL), and the organic phase was washed with 1 M sodium hydroxide (20 mL) and saturated ammonium chloride (20 mL), dried with anhydrous magnesium sulfate, filtered, and concentrated in vacuo. The residue was purified by column chromatography, eluting with a gradient of 5 to 90% ethyl acetate in heptane. Further purification by reverse-phase column chromatography, using a gradient of 10 to 95% acetonitrile in water as eluent, afforded a single diastereomer as colorless solid (0.064 g, 41% yield):  1 H NMR (400 MHz, DMSO-d 6 ) δ 10.63 (d, J=0.5 Hz, 1H), 9.23 (s, 1H), 8.98 (s, 2H), 7.41-7.32 (m, 3H), 3.78-3.68 (m, 1H), 3.20 (7, J=6.9 Hz, 1H), 2.91-2.81 (m, 1H), 2.47-2.40 (m, 1H), 2.09-1.92 (m, 2H), 1.84-1.67 (m, 3H), 1.52-1.39 (m, 2H), 1.29 (d, J=6.9 Hz, 6H); MS (ES+) m/z 506.3 (M+1).

     As disclosed above, typical assays for testing compounds of the disclosure are known, for example as disclosed in Crestey, F. et al.,  ACS Chem Neurosci  (2015), Vol. 6, pp. 1302-1308, AA43279 (Frederiksen, K. et al.,  Eur J Neurosci  (2017), Vol. 46, pp. 1887-1896) and Lu AE98134 (von Schoubyea, N. L. et al.,  Neurosci Lett  (2018), Vol. 662, pp. 29-35) which employs the use of automated planar patch clamp techniques to study the effects of the chemical agent on the gating of sodium channels. The sodium channel isoforms of interest are stably expressed in Human Embryonic Kidney Cells and the currents that flow through those channels in response to a depolarizing voltage clamp step from −120 mV to 0 mV are measured in the presence of increasing concentrations of the chemical agents. The area under the sodium current trace which correlates to the magnitude of sodium flux through the cell mebrane is used to quantify the effects on gating of the channels. Other parameters that are measured in the assay include the peak current, time constant of open state inactivation and the voltage dependence of steady state inactivation properties. The concentration responses are used to determine potency of each chemical agents effects on modulating the sodium channel isoform gating.
