Procedure

To a solution of (1R,3S)-3-isopropyl-3-(4-[6-methyl-4-(trifluoromethyl)pyridin-2-yl]piperazin-1-ylcarbonyl)cyclopentanamine (120 mg, 0.30 mmol), 3-methoxytetrahydro-4H-pyran-4-one (120 mg, 0.90 mmol), and triethylamine (0.12 mL, 0.90 mmol) in methylene chloride (20 mL) was added sodium triacetoxyborohydride (0.19 g, 0.90 mmol). After being stirred at room temperature overnight, the reaction mixture was diluted with methylene chloride, washed with brine, dried over sodium sulfate, filtered and concentrated. The residue was purified by flash chromatography to provide the desired product as a mixture of cis/trans isomers. LCMS calculated for C26H40F3N4O3: (M+H) 513.3; found 513.2 for both isomers.
