Reaction Steps

(b)(c) To a stirred solution of (S)-2,2-dimethyl-3-(1-methyl-1H-indazol-5-yl)-3-phenylpropanenitrile (54 mg, 0.193 mmol) in anhydrous THF (10 mL) was added 1.0M lithium aluminum hydride in diethyl ether (0.5 mL, 0.5 mmol) portionwise at RT under nitrogen. After stirring at RT for 3 hr, the mixture was carefully quenched with MeOH, poured into brine, extracted with ethyl acetate (2×100 mL), dried (MgSO4) and concentrated. The crude product was coupled with 3,3,3-trifluoropropanoic acid (29 mg, 0.226 mmol) using General Coupling Method A to give 40 mg (51% yield) of (S)—N-(2,2-dimethyl-3-(1-methyl-1H-indazol-5-yl)-3-phenylpropyl)-3,3,3-trifluoropropanamide. MS found: (M+H)+=404.
