Process Aspect In general, the compounds of this invention may be prepared by various reactants and processes known in the art. Illustrative but not limiting as the reactants and processes utilized for the preparation of the compounds of the invention are the following Schemes A-H and J: As depicted in Scheme A, treating methyl aminobenzoates 1 under typical Debus conditions (NH 4 OH, formaldehyde and glyoxal) affords methyl imidazolylbenzoates 2 . Reaction of methyl aminobenzoates 1 with various alkylsulfonyl chlorides in pyridine and methylene chloride, usually at about 0°C, gives methyl alkylsulfonylaminobenzoates 2 . Compounds 2 , when treated with aqueous sodium hydroxide, give the sodium salts 3 . Acid chloride formation follows when the sodium salt 3 is treated with thionyl chloride (neat) or in refluxing toluene. Amides 5 are prepared when acid chlorides 4 are treated with 1-benzylpiperazine in a solvent such as tetrahydrofuran. Hydrogenolysis of the benzyl group occurs when the amides 5 are treated with hydrogen gas and a catalyst such as palladium on carbon. Common solvents for this hydrogenolysis are water, ethanol, methanol and various mixtures thereof. Compounds 7 of this invention are prepared when amide 6 is mixed with known in the art epoxides in methanol. Compounds 9 are prepared by treating amides 6 with α-haloketones and Huenigs base in acetonitrile and subsequently reducing the ketone moiety of 8 under standard hydrogenation conditions (H 2 , Pd-C, MeOH/H 2 O). Scheme B summarizes the process for preparing compounds 13 and 15 where ALK=CH 2 . Treatment of aminobenzonitriles 10 under typical Debus conditions give imidazolylbenzonitriles 11 . Aminobenzonitriles 10 can be alkylsulfonylated giving 11 , using various alkylsulfonylchlorides in pyridine and methylene chloride. Reduction of the cyano moiety of 11 using hydrogen gas (∼50 psi) and a Raney-Nickel catalyst in ammonia/methano] produces alkylamines 12 . Treating 12 with known in the art epoxides in a solvent such as methanol gives compounds 13 . Compounds 15 are prepared by reacting 12 with α-halo ketones and Huenig's base in acetonitrile and subsequently reducing the ketone moiety of 14 under standard hydrogenation conditions (H 2 , Pd-C, MeOH/H 2 O). Scheme C summarizes the preparation of compounds 13 and 15 where ALK has the meaning described above in the specification and claims section of this invention. Generally nitrophenalkyl halides 16 are treated with sodium phthalimide in a solvent such as dimethylformamide and give nitrophthalimides 17 . Reduction of the nitro moiety by the method of Bellamy (SnCl 2 , EtOH) gives aminophthalimides 18 after work up. Imidazole formation via the Debus reaction (NH 4 OH, formaldehyde, glyoxal) follows to give 19 . Alkylsulfonylamino derivatives 19 are prepared by treatment of 18 with various alkylsulfonyl chlorides in pyridine and methylene chloride. Cleavage of the phthalimide moiety of 19 using hydrazine hydrate in refluxing ethanol yields alkylamines 12 . Compounds 12 are employed to produce 13 and 15 using the general method outlined in Scheme B. Preparations of compounds 24 and 26 of this invention are summarized in Scheme D. Treatment of 1-fluoro-4-nitrobenzene and 1-benzylpiperazine in acetonitrile with potassium carbonate affords nitrophenylpiperazine 20 . Reduction of the nitro group using tin chloride in ethanol gives aminophenylpiperazine 21 . When 21 is stirred with a mixture of ammonia, formaldehyde and glyoxal (Debus conditions) imidazole 22 is formed. Treating 21 with various alkylsulfonic anhydrides in a solvent such as acetonitrile produces alkylsulfonylamides 22 . Hydrogenolysis of the benzyl group of 22 is carried out using standard conditions (H 2 , Pd-C, EtOH/H 2 O) and yields 23 . Reaction of 23 with known in the art epoxides in mixtures of methanol and water give compounds 24 . Compounds 26 are prepared by treating 23 with α-haloketones and Huenig's base in acetonitrile and subsequently reducing the ketone moiety of 25 using standard reduction conditions (H 2 , Pd-C, MeOH/H 2 O). The corresponding 3-imidazoly] derivatives 31 and 33 are prepared by analogous synthetic methods to those used for 24 and 26 via Scheme E. The only difference is that compound 27 is produced from the treatment of 3-nitroaniline with N,N-bis(2-chloroethyl)benzylamine hydrochloride in ethanol containing potassium carbonate. Compound 27 is carried through the same synthetic sequences as 20 (Scheme D) and provides compounds 31 and 33 of this invention. The synthetic sequences for preparing compounds 37 and 39 is summarized in Scheme F. Imidazolyl-phenols 34 can be alkylated with various chloroalkylamines or chloroalkylbenzylamines with sodium hydride in dimethylformamide to give imidazole-amines 35 and 36 , respectively. Treatment of 35 with various epoxides in methanol/water affords compounds 37 . Reaction of imidazole-amines 36 with α-haloketones and Huenigs base in acetonitrile yields imidazole-ketones 38 . Standard reduction of 38 (H 2 , Pd-C, MeOH/H 2 O) gives compound 39 of this invention. Compounds 45 and 47 of this invention can be synthesized by the sequence shown in Scheme G. Nucleophilic aromatic substitution of 1-fluoro-4-nitrobenzene with various dibenzylaminoalcohols using sodium hydride in dimethylformamide and tetrahydrofuran affords nitrodibenzylamines 40 . Reduction of the nitro group (SnCl 2 , EtOH) followed by alkylsulfonylation in acetonitrile yields dibenzylamines 42 . Monodebenzylation of 42 can be achieved under standard hydrogenolysis conditions (H 2 , Pd-C, EtOH/H 2 O) to gibe benzylamines 43 . Complete debenzylation of 42 can be accomplished under more vigorous conditions (H 2 , Pd(OH) 2 , HOAc, ∼50 psi) and affords amines 44 . Amines 43 and 44 can be carried through the same synthetic sequences as amines 36 and 35 (Scheme F) to give compounds 45 and 47 of this invention. Dibenzylamines 49 can be prepared by reacting various dibenzyldiamines with either benzenesulfonyl chlorides or benzoyl chlorides 48 in a solvent such as tetrahydrofuran (Scheme H). Compounds 49 can be carried through the same sequences as compounds 42 (Scheme G) to produce compounds 52 and 54 of this invention. An alternate way of preparing 52 follows from Scheme J. Methyl imidazolylbenzoates 55 can be heated with various alkanediamines to give amines 50 . Treating 50 with epoxides known in the art yields compounds 52 of this invention. In general the methods for preparing the optically active enantiomers of the compounds of Formula I follow standard procedures. For instance, to produce the compounds of Formula I wherein x is the integer 1, the corresponding epoxides are formed from the optically active epicholorohydrins or tosylates. In the instance where x is the integer 0 the compounds, via one procedure, are prepared from the corresponding racemates by classical resolution procedures i.e., optically active acids forming diastereomeric salts which are separated then converted to the free bases to produce the corresponding enantiomers. Method-of-Use and Pharmaceutical Composition Aspect The novel alkanolamines of this invention derivatized by at least a imidazol-1-ylphenyl or alkylsulfonylaminophenyl moiety and their pharmaceutically acceptable salts are cardiovascular agents. Most especially within the aegis of cardiovascular pharmacology, these compounds have been specifically designed to provide a combination beta-adrenergic blockade with electrophysiologic activity to selectively prolong cellular refractoriness. According to the Vaughan Williams classification, such agents would have Class II/Class III antiarrhythmic effect. Such combination contains those therapeutic effects attributed to Class II and Class III antiarrhythmic agents singly. In the Vaughan Williams classification of antiarrhythmic agents, Class II agents are the β-adrenergic blocking agents, which so called β-blockers decrease the sensitivity of the cardiac tissue to catecholamines. The catecholamines in excess can increase the electrical instability of the heart. Class II agents are exemplified by propranolol, metoprolol, nadolol, timolol, atenolol, sotalol, acebutolol and nipradilol. The Class III agents prolong the action potential duration of the heart thus increasing the time interval in which the heart is unexcitable (refractory period) without slowing conduction or changing the excitability of the cardiac cells. These agents have little or not effect on conduction, in fact, they are quite independent of conduction. Such agents are exemplified in the literature by bretylium, amiodarone, clofilium, melperone and sematilide (the latter compound developed in these laboratories). Several investigators have demonstrated that the arrhythmia responsible for sudden cardiac death is ventricular fibrillation (VF). VF has been shown to occur via a reentrant mechanism. Reentrant ventricular arrhythmias can occur as a result of abnormalities in conduction and/or refractoriness. In a reentrant arrhythmia, a single cardiac impulse follows a circular pathway, allowing repeated excitation of the same tissue. One approach to the abolition of such reentrant arrhythmias is to further prolong the refractory period of cardiac cells, such that the impulse, upon returning to its point of origin, is met with refractory tissue and propagation of the impulse if stopped. This is clearly the therapeutic rationale behind the development of agents possessing Class III activity. Reentrant arrhythmias often are initiated or "triggered" by an appropriately timed premature impulse. In patients following myocardial infarction, excessive catecholamine levels may be responsible for triggering many arrhythmias which may be associated with sudden cardiac death. In fact, the results of several large, multi-center trials have shown that beta-adrenergic blockers can reduce mortality from sudden cardiac death in post-infarction patients. Presumably, beta-blockers work by decreasing the sensitivity of the heart to catecholamines, and thereby decrease the potential "triggering" event which leads to reentrant ventricular arrhythmias. The overall decrease in mortality from these studies is approximately 25%, suggesting that beta-adrenergic blockade when used alone offers no beneficial antiarrhythmic effect in the remaining majority of post-infarction patients. Clinical data such as these highlight the multiple etiologies present in patients dying of sudden cardiac death and the need for a more "broad spectrum" approach. One broad spectrum approach is to produce an agent with both Class II and Class III properties. Several investigators have shown that an increase in sympathetic tone to the heart will shorten refractoriness, an action which can be blocked by beta-adrenergic antagonists. Preliminary data using the selective Class III agent clofilium have shown that its Class III actions are blunted in the setting of enhanced sympathetic tone (Sullivan and Steinberg, 1981). Furthermore preliminary studies performed in conscious dogs in these laboratories suggest a synergistic effect between inhibition of beta-receptors and prolongation of refractoriness. In pilot studies utilizing programmed electrical stimulation (PES) techniques to induce reentrant arrhythmias, a sub-therapeutic dose of sematilide was administered and shown not to be efficacious. Subsequent administration of a beta-blocking dose of propranolol (0.5 mg/kg, i.v.) was shown to protect the heart from PES-induced arrhythmias. Previous studies in these laboratories have demonstrated that propranolol when used alone is not efficacious in this model. In animals receiving the combination therapy, ventricular refractory period increased 8% following sematilide and 18% with the addition of propranolol. Propranolol, when used alone at this dose, had no effect on refractoriness. These data suggest a synergistic action between Class III and Class II agents and that modulation of beta-adrenergic tone can enhance the Class III properties of certain agents. Sotalol can be considered the prototype drug for an agent with both Class II and Class III activity. Experimental and clinical data suggest that the beta-blocking effect of sotalol begins at doses lower or equivalent to doses which produce its Class III actions. Thus, the compounds of this invention are designed to have a more potent Class III action relative to their Class II potency in order to demonstrate a distinct advantage in the setting of reentrant ventricular arrhythmias. The compounds of this invention have been tested for their Class III activity via in vitro electrophysiologic testing utilizing standard intracellular microelectrode techniques in the canine cardiac Purkinje fiber. They were then tested for reasonable β-adrenergic blocking activity as measured in the in vitro screens of isolated papillary muscle (inhibition of the inotropic response to epinephrine) and the beta-adrenergic binding screen (displacement of radiolabelled dihydroalprenolol). They were then assessed in the in vivo model of the pentobarbital anesthetized dog in which the compound was administered intraduodenally and its Class III (increase in functional refractory period) and Class II (inhibition of isoproterenol response) effects were monitored.

In essence, the physician has been provided with a simple chemical entity providing 2 effects thereby mitigating the problems of multiple drug therapy, e.g. side effects, metabolic problems, drug interactions, etc. and the problems in patient compliance - different drugs, different therapeutic regimens. The compounds whilst preferably utilized in the treatment of mammalian arrhythmias and most specifically used in the treatment of mammalian arrhythmias in need of combination Class II/III effects, possess some general cardiovascular properties. Some of the compounds may, due to the level of Class II effects, exhibit an anti-hypertensive effect. In general, the compounds of this invention may be administered orally or parenterally. The dosage administered will depend on the subject being treated, the route of administration and the type and severity of the arrhythmias being prevented or reduced. The compound to be administered can be formulated by admixing with any of a number of suitable pharmaceutical diluents and carriers such as lactose, sucrose, starch powder, cellulose, calcium sulfate, sodium benzoate and the like. Such formulations can be compressed into tablets or can be encapsulated into gelatin capsules for convenient oral administration. Such a capsule may contain one of the compounds of this invention for example, N-[4-[4-[2-hydroxy-3-(2-methylphenoxy)propyl]piperazin-1-]phenyl]methanesulfonamide, N-[4-[2-hydroxy-3-[[2-[4-(1H-imidazol-1-yl)phenoxy]ethyl]amino]propoxy]phenyl]methanesulfonamide or N-[4-[1-hydroxy-2-[[2-[4-(1H-imidazol-1-yl)phenoxy]ethyl]amino]ethyl]phenyl]methanesulfonamide in the amount of about 1 to about 500 mg. Such formulation can be administered orally at the rate of about 1 to 4 capsules per day or more often as needed, depending upon the particular condition and subject being treated. For parenteral administration a compound of this invention can be formulated as an intramuscular or intravenous medicament but is not limited thereto. In the case of treatment of a patient suffering from severe cardiac arrhythmias, it may be desirable to administer a compound of the invention by intravenous slow bolus in order to effect a rapid conversion to a normal sinus rhythm. The normalized condition can then be maintained by oral administration. The compounds of this invention can be formulated for parenteral administration with any of a number of pharmaceutically acceptable carriers and diluents to constitute an injectable liquid solution. Commonly used diluents and carriers include water or a saline solution, buffered aqueous solutions as well as dispersing and surface active agents if necessary. A typical formulation suited to intravenous or intramuscular administration may contain one of the compounds of this invention such as N-[4-[4-[2-hydroxy-3-(2-methylphenoxy)propyl]piperazin-1-]phenyl]methanesulfonamide in the amount of about 50 to 150 mg and a solubilizing agent and sufficient sterile water to bring the volume to about 5ml-100ml. Such formulation can be infused at a constant rate or injected one to four times per day or more often depending upon the particular condition of the subject being treated. It is further contemplated that the compounds of this invention may be formulated into sublingual lozenges or impregnated into fabric appliques for a type of transdermal application.
