CROSS-REFERENCE 
     This application claims the benefit of Indian Application No. 202011016737 filed Apr. 18, 2020 which is hereby incorporated by reference in its entirety. 
     BACKGROUND OF THE INVENTION 
     Nonalcoholic fatty liver diseases (NAFLDs) including NASH (nonalcoholic steatohepatitis) are considered to be hepatic manifestations of the metabolic syndrome and are characterized by the accumulation of triglycerides in the liver of patients without a history of excessive alcohol consumption. The majority of patients with NAFLD are obese or morbidly obese and have accompanying insulin resistance. The incidence of NAFLD/NASH has been rapidly increasing worldwide consistent with the increased prevalence of obesity, and it is currently the most common chronic liver disease. 
     NAFLD is classified into simple steatosis, in which only hepatic steatosis is observed, and NASH, in which intralobular inflammation and ballooning degeneration of hepatocytes is observed along with hepatic steatosis. The proportion of patients with NAFLD who have NASH is still not clear but might range from 20-40%. NASH is a progressive disease and may lead to liver cirrhosis and hepatocellular carcinoma. Twenty percent of NASH patients are reported to develop cirrhosis, and 30-40% of patients with NASH cirrhosis experience liver-related death. Recently, NASH has become the third most common indication for liver transplantation in the United States. Currently, the principal treatment for NAFLD/NASH is lifestyle modification by diet and exercise. However, pharmacological therapy is indispensable because obese patients with NAFLD often have difficulty maintaining improved lifestyles. 
     17β-Hydroxysteroid dehydrogenases (HSD17Bs) comprise a large family of 15 members that are mainly involved in sex hormone metabolism. Some HSD17Bs enzymes also play key roles in cholesterol and fatty acid metabolism. A recent study showed that hydroxysteroid 17β-dehydrogenase 13 (HSD17B13), an enzyme with unknown biological function, is a novel liver-specific lipid droplet (LD)-associated protein in mouse and humans. HSD17B13 expression is markedly upregulated in patients and mice with non-alcoholic fatty liver disease (NAFLD). Hepatic overexpression of HSD17B13 promotes lipid accumulation in the liver. HSD17B13 could also have potential as a biomarker of chronic liver disease, such as alcoholic liver disease (ALD), non-alcoholic fatty liver disease (NAFLD) (for example: steatosis, nonalcoholic steatohepatitis (NASH), NASH-fibrosis, or cirrhosis), steatohepatitis, and liver cancer.

For example, “optionally substituted alkyl” means either “alkyl” or “substituted alkyl” as defined above. Further, an optionally substituted group may be un-substituted (e.g., —CH 2 CH 3 ), fully substituted (e.g., —CF 2 CF 3 ), mono-substituted (e.g., —CH 2 CH 2 F) or substituted at a level anywhere in-between fully substituted and mono-substituted (e.g., —CH 2 CHF 2 , —CH 2 CF 3 , —CF 2 CH 3 , —CFHCHF 2 , etc.). It will be understood by those skilled in the art with respect to any group containing one or more substituents that such groups are not intended to introduce any substitution or substitution patterns (e.g., substituted alkyl includes optionally substituted cycloalkyl groups, which in turn are defined as including optionally substituted alkyl groups, potentially ad infinitum) that are sterically impractical and/or synthetically non-feasible. Thus, any substituents described should generally be understood as having a maximum molecular weight of about 1,000 daltons, and more typically, up to about 500 daltons. 
     An “effective amount” or “therapeutically effective amount” refers to an amount of a compound administered to a mammalian subject, either as a single dose or as part of a series of doses, which is effective to produce a desired therapeutic effect.

In some embodiments, treatment includes administration of a pharmaceutical composition, subsequent to the initiation of a pathologic event or contact with an etiologic agent and includes stabilization of the condition (e.g., condition does not worsen) or alleviation of the condition. In some embodiments, treatment also includes prophylactic treatment (e.g., administration of a composition described herein when an individual is suspected to be suffering from a liver disease, e.g., NAFLD). 
     “Synergy” or “synergize” refers to an effect of a combination that is greater than additive of the effects of each component alone at the same doses. 
     “HSD17B13” means hydroxysteroid 17-beta dehydrogenase 13 and refers to any nucleic acid of HSD17B13. For example, in some embodiments, HSD17B13 includes a DNA sequence encoding HSD17B13, an RNA sequence transcribed from DNA encoding HSD17B13 (including genomic DNA comprising introns and exons). HSD17B13 can also refer to any amino acid sequence of HSD17B13 (may include secondary or tertiary structures of the protein molecule), encoded by a DNA sequence and/or RNA sequence. The target may be referred to in either upper or lower case.

     Further Forms of Compounds Disclosed Herein 
     Isomers Stereoisomers 
     In some embodiments, the compounds described herein exist as geometric isomers. In some embodiments, the compounds described herein possess one or more double bonds. The compounds presented herein include all cis, trans, syn, anti, entgegen (E), and zusammen (Z) isomers as well as the corresponding mixtures thereof. In some situations, the compounds described herein possess one or more chiral centers and each center exists in the R configuration, or S configuration. The compounds described herein include all diastereomeric, enantiomeric, and epimeric forms as well as the corresponding mixtures thereof. In additional embodiments of the compounds and methods provided herein, mixtures of enantiomers and/or diastereoisomers, resulting from a single preparative step, combination, or interconversion are useful for the applications described herein. In some embodiments, the compounds described herein are prepared as their individual stereoisomers by reacting a racemic mixture of the compound with an optically active resolving agent to form a pair of diastereoisomeric compounds, separating the diastereomers and recovering the optically pure enantiomers. In some embodiments, dissociable complexes are preferred. In some embodiments, the diastereomers have distinct physical properties (e.g., melting points, boiling points, solubilities, reactivity, etc.) and are separated by taking advantage of these dissimilarities. In some embodiments, the diastereomers are separated by chiral chromatography, or preferably, by separation/resolution techniques based upon differences in solubility. In some embodiments, the optically pure enantiomer is then recovered, along with the resolving agent, by any practical means that would not result in racemization.

     Dosing 
     In certain embodiments, the compositions containing the compound(s) described herein are administered for prophylactic and/or therapeutic treatments. In certain therapeutic applications, the compositions are administered to a patient already suffering from a disease or condition, in an amount sufficient to cure or at least partially arrest at least one of the symptoms of the disease or condition. Amounts effective for this use depend on the severity and course of the disease or condition, previous therapy, the patient&#39;s health status, weight, and response to the drugs, and the judgment of the treating physician. Therapeutically effective amounts are optionally determined by methods including, but not limited to, a dose escalation and/or dose ranging clinical trial. 
     In prophylactic applications, compositions containing the compounds described herein are administered to a patient susceptible to or otherwise at risk of a particular disease, disorder or condition. Such an amount is defined to be a “prophylactically effective amount or dose.” In this use, the precise amounts also depend on the patient&#39;s state of health, weight, and the like. When used in patients, effective amounts for this use will depend on the severity and course of the disease, disorder or condition, previous therapy, the patient&#39;s health status and response to the drugs, and the judgment of the treating physician. In one aspect, prophylactic treatments include administering to a mammal, who previously experienced at least one symptom of or risk factor for the disease being treated and is currently in remission, a pharmaceutical composition comprising a compound described herein, or a pharmaceutically acceptable salt thereof, in order to prevent a return of the symptoms of the disease or condition. In one aspect, prophylactic treatments include administering to a mammal having patatin-like phospholipase domain-containing 3 (PNPLA3) polymorphism, a pharmaceutical composition comprising a compound described herein, or a pharmaceutically acceptable salt thereof, in order to prevent liver damages. The 148 Isoleucine to Methionine protein variant (I148M) of patatin-like phospholipase domain-containing 3 (PNPLA3), a protein is expressed in the liver and is involved in lipid metabolism, has recently been identified as a major determinant of liver fat content. Several studies confirmed that the I148M variant predisposes towards the full spectrum of liver damage associated with fatty liver: from simple steatosis to steatohepatitis and progressive fibrosis. Furthermore, the I148M variant represents a major determinant of progression of alcohol related steatohepatitis to cirrhosis, and to influence fibrogenesis and related clinical outcomes in chronic hepatitis C virus hepatitis, and possibly chronic hepatitis B virus hepatitis, hereditary hemochromatosis and primary sclerosing cholangitis. In some embodiments, PNPLA3 polymorphism is used to predict liver disease progression. 
     In certain embodiments wherein the patient&#39;s condition does not improve, upon the doctor&#39;s discretion the administration of the compounds are administered chronically, that is, for an extended period of time, including throughout the duration of the patient&#39;s life in order to ameliorate or otherwise control or limit the symptoms of the patient&#39;s disease or condition. 
     In certain embodiments wherein a patient&#39;s status does improve, the dose of drug being administered is temporarily reduced or temporarily suspended for a certain length of time (i.e., a “drug holiday”). In specific embodiments, the length of the drug holiday is between 2 days and 1 year, including by way of example only, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 10 days, 12 days, 15 days, 20 days, 28 days, or more than 28 days. The dose reduction during a drug holiday is, by way of example only, by 10%-100%, including by way of example only 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, and 100%. 
     Once improvement of the patient&#39;s conditions has occurred, a maintenance dose is administered if necessary. Subsequently, in specific embodiments, the dosage or the frequency of administration, or both, is reduced, as a function of the symptoms, to a level at which the improved disease, disorder or condition is retained. In certain embodiments, however, the patient requires intermittent or daily treatment on a long-term basis upon any recurrence of symptoms. 
     The amount of a given agent that corresponds to such an amount varies depending upon factors such as the particular compound, disease condition and its severity, the identity (e.g., weight, sex) of the subject or host in need of treatment, but nevertheless is determined according to the particular circumstances surrounding the case, including, e.g., the specific agent being administered, the route of administration, the condition being treated, and the subject or host being treated. 
     In general, however, doses employed for adult human treatment are typically in the range of 0.01 mg-5000 mg per day. In one aspect, doses employed for adult human treatment are from about 1 mg to about 1000 mg per day. In one embodiment, the desired dose is conveniently presented in a single dose or in divided doses administered simultaneously or at appropriate intervals, for example as two, three, four or more sub-doses per day. 
     In one embodiment, the daily dosages appropriate for the compound described herein, or a pharmaceutically acceptable salt thereof, are from about 0.01 to about 50 mg/kg per body weight. In some embodiments, the daily dosage or the amount of active in the dosage form are lower or higher than the ranges indicated herein, based on a number of variables in regard to an individual treatment regime. In various embodiments, the daily and unit dosages are altered depending on a number of variables including, but not limited to, the activity of the compound used, the disease or condition to be treated, the mode of administration, the requirements of the individual subject, the severity of the disease or condition being treated, and the judgment of the practitioner. 
     Toxicity and therapeutic efficacy of such therapeutic regimens are determined by standard pharmaceutical procedures in cell cultures or experimental animals, including, but not limited to, the determination of the LD 10  and the ED 90 . The dose ratio between the toxic and therapeutic effects is the therapeutic index and it is expressed as the ratio between LD 50  and ED 50 . In certain embodiments, the data obtained from cell culture assays and animal studies are used in formulating the therapeutically effective daily dosage range and/or the therapeutically effective unit dosage amount for use in mammals, including humans. In some embodiments, the daily dosage amount of the compounds described herein lies within a range of circulating concentrations that include the ED 50  with minimal toxicity. In certain embodiments, the daily dosage range and/or the unit dosage amount varies within this range depending upon the dosage form employed and the route of administration utilized. 
     In any of the aforementioned aspects are further embodiments in which the effective amount of the compound described herein, or a pharmaceutically acceptable salt thereof, is: (a) systemically administered to the mammal; and/or (b) administered orally to the mammal; and/or (c) intravenously administered to the mammal; and/or (d) administered by injection to the mammal; and/or (e) administered topically to the mammal; and/or (f) administered non-systemically or locally to the mammal. 
     In any of the aforementioned aspects are further embodiments comprising single administrations of the effective amount of the compound, including further embodiments in which (i) the compound is administered once a day; or (ii) the compound is administered to the mammal multiple times over the span of one day. 
     In any of the aforementioned aspects are further embodiments comprising multiple administrations of the effective amount of the compound, including further embodiments in which (i) the compound is administered continuously or intermittently: as in a single dose; (ii) the time between multiple administrations is every 6 hours; (iii) the compound is administered to the mammal every 8 hours; (iv) the compound is administered to the subject every 12 hours; (v) the compound is administered to the subject every 24 hours. In further or alternative embodiments, the method comprises a drug holiday, wherein the administration of the compound is temporarily suspended or the dose of the compound being administered is temporarily reduced; at the end of the drug holiday, dosing of the compound is resumed. In one embodiment, the length of the drug holiday varies from 2 days to 1 year.

     To a stirred solution of 2,4-difluoro-3-methoxyphenol (0.53 g, 3.36 mmol) in acetone (5.0 mL) and water (2.0 mL) was added sodium hydroxide (0.13 g, 3.36 mmol) and stirred for 20 minutes followed by the addition of 2,4-dichloropyrimidine (0.5 g, 3.36 mmol), the reaction mixture was then stirred at ambient temperature for 3 hours. The reaction mixture was evaporated under vacuo and added ice cold water (10 mL), obtained solid was filtered, washed with water (20 mL) and dried to afford 2-chloro-4-(2,4-difluoro-3-methoxyphenoxy)pyrimidine (0.72 g, 80%) as a white solid. LCMS (ES) m/z calcd. for C11H7ClF2N2O2, 272.02; found, 273.0 (M+H). 
     Step 2: Synthesis of 4-(4-(4-(2,4-difluoro-3-methoxyphenoxy)pyrimidin-2-yl)phenyl)morpholine 
     To a stirred solution of 2-chloro-4-(2,4-difluoro-3-methoxyphenoxy)pyrimidine (200 mg, 0.734 mmol) and [4-(morpholin-4-yl)phenyl]boronic acid (182 mg, 0.88 mmol) in 1,4-dioxane (5.00 mL) and water (1.00 mL), was added cesium carbonate (717 mg, 2.20 mmol). Reaction mixture was purged with Argon gas. To this was added Pd(dppf)Cl 2  (53.7 mg, 0.073 mmol) and then heated to 100° C. for 16 h. The reaction mixture was cooled to room temperature and quenched with water (10 mL), extracted with ethyl acetate (10 mL). The organic layer was dried over anhydrous sodium sulfate and concentrated under vacuo to obtain crude. The crude was purified by flash chromatography to afford 4-(4-(4-(2,4-difluoro-3-methoxyphenoxy)pyrimidin-2-yl)phenyl)morpholine (0.185 g, 63%) as a white solid.

     Example A: NADH Detection Assay for Evaluation of HSD17ß13 Activity and Identification of Inhibitors 
     The fluorescence based Leukotriene B3 (LTB3) assay monitors the fluorescence of NADH, which is generated from NAD+ during the dehydrogenation of the substrate LTB3. The reactions were performed in a 384-well plates (Greiner; #655076) in a 20 μl reaction volume containing the following reagents (final concentrations): 25 μM LTB3 (Cayman; #20109); 3 mM NAD+ (Sigma; #N0623); 125 nM HSD17B13 enzyme (in-house;  E. coli  expressed His-tagged, purified, soluble protein); 1 M potassium phosphate buffer, pH 7.4; and 1% DMSO. Reactions were initiated by co-addition of NAD+ and enzyme, and monitored for 1 hour at 26.5° C. Generation of NADH was measured as the fluorescence signal (Excitation at 340 nm and Emission at 445 nm) at 1 hour minus the baseline fluorescence at t=0. Fluorescence signals in the absence of LTB3 (negative control values), were subtracted from all values so that the results reflected substrate-dependent production of NADH. NADH standards were included to allow the conversion of relative fluorescence units into rates of enzyme activity. Enzyme activity in the presence of test compounds was expressed as a percentage of the uninhibited enzyme activity, and plotted versus inhibitor concentration. Non-linear regression was performed using a four-parameter logistic model and GraphPad Prism software (GraphPad Software, La Jolla, Calif.). Ten concentrations of inhibitor were tested (in the range of 30 μM-2.5 nM), and two independent assessments were performed at each concentration. The data are is shown in table 2 below:

     Example B: Estrone Detection Assay for Evaluation of HSD17ß13 Activity and Identification of Inhibitors 
     The liquid chromatography/mass spectrometry (LC/MS) estrone detection assay monitors the conversion of estradiol to estrone by HSD17B13. This assay was undertaken in a 96wp format (Eppendorf deep well Plate 96/500) in an 80 μl reaction volume containing: 4 μM of Estradiol (E2; Cayman; Ser. No. 10/006,315), 6 mM NAD+(Sigma; #N0623) and 30 nM HSD17B13 enzyme (in-house;  E. coli  expressed His-tagged, purified, soluble protein) in a reaction containing 1M potassium phosphate buffer pH 7.4, with 0.5% vehicle (DMSO). Reactions were incubated for 2 hours at 26.5° C., and estradiol (E2) conversion to estrone (E1) was quantitated by LC-MS/MS based analyte detection for both E2 and E1 using LCMS grade reagents. 
     Reactions were terminated by the addition of two volumes of acetonitrile (MeCN; LCMS grade; CAS #75/05/8) containing deuterated (D4)-E1 used as internal standard (Clear Synth; #CS-T-54273; 500 ng/mL final concentration). Samples were applied to pre-prepared Bond Elut-C18 extraction cartridges (3 mL; Agilent; Ser. No. 12/102,028), washed and eluted in MeCN. Eluates were dried under nitrogen and re-suspended in 60% methanol (LCMS grade methanol; CAS #67/56/1) before submission for analysis. Aqueous linearity for E2 and E1 were included for quantification. 
     Analysis of samples was undertaken on a XBridge BEH C18 column (Waters; #186003033) using 0.1% Diethyl Amine in MeCN (mobile phase A; DEA CAS #109-89-7) and 0.1% Diethyl Amine in milli-Q water (mobile phase B) in a 3 min gradient allowing 25% B. Analytes were detected in negative mode using MRM analysis, with E2 having a RT of 1.85 min and E1 having a RT of 2 min. Activity of the enzyme, in the absence of NAD+, was used to evaluate specificity of conversion. Enzyme activity in the presence of test samples was expressed as a percentage of the uninhibited enzyme activity, and plotted versus inhibitor concentration. Non-linear regression was performed using a four-parameter logistic model and GraphPad Prism software (GraphPad Software, La Jolla, Calif.). All assessments were undertaken in duplicate evaluations and pooled during extraction process and subsequently injected as duplicates for LC-MS/MS analysis.
