Participants

Reaction Steps

To a stirred solution of 250 mg (0.79 mmol) of (S)-1-[(3R,4S)-1-Benzyl-4-(4-chloro-phenyl)-pyrrolidin-3-yl]-ethanol in DMF (10 mL) was added NaH (57 mg, 1.18 mmol). The reaction mixture was stirred at RT for 30 minutes, and then at 50° C. for 20 minutes. A solution of 2-chloro-5-trifluoromethyl-pyridine (172 mg, 0.95 mmol) in DMF (2 mL) was added dropwise and stirring was continued 3 hours at 50° C. The reaction mixture was concentrated under vacuo. Extraction with EtOAc/H2O, followed by column chromatography (SiO2, EtOAc/H, 1:4) yielded 350 mg (96%) of the title compound as a colorless oil. ES-MS m/e: 461.3 (M+H+).
