Procedure

Into a round-bottom flask was added 3-(4-trifluoromethyl-phenoxymethyl)-piperidin-3-ol (100 mg, 0.36 mmol), dichloromethane (S mL), diisopropylethylamine (0.190 mL, 1.08 mmol), 1-(4-chloro-phenyl)-cyclobutanecarboxylic acid (113.4 mg, 0.54 mmole), and PyBroP (0.252 g, 0.54 mmol). The reaction mixture was stirred at room temperature overnight. The reaction mixture was diluted with water and then extracted with ethyl acetate (3×10 mL). The extracts were combined, dried over anhydrous sodium sulfate, filtered, and concentrated to give a yellow oil. The oil was purified by column chromatography on silica gel using hexane/ethyl acetate (4:1) to give [1-(4-Chloro-phenyl)-cyclobutyl]-[3-hydroxy-3-(4-trifluoromethyl-phenoxymethyl)-piperidin-1-yl]-methanone (18.7 mg, 11%). MH+ (468).
