Procedure

To a mixture of ethyl (3R)-1-(4-((4,4,4-trifluoro-1-(2-methyl-4-(4,5,6,7-tetrahydro-2H-indazol-2-yl)phenyl)butyl)amino)benzoyl)piperidine-3-carboxylate (9.61 g), THF (32 mL) and ethanol (32 mL) was added 1M aqueous sodium hydroxide solution (32.2 mL), and the mixture was stirred at room temperature for 2 hr. The solvent was evaporated under reduced pressure, the reaction mixture was neutralized with 1M hydrochloric acid (32.2 mL), and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure to give the title compound as a crudely purified product. The crudely purified product obtained here and separately synthesized crudely purified product (1.68 g) were combined, and recrystallized from a mixed solvent of ethyl acetate-hexane to give the title compound (8.49 g).
