Procedure

To a stirred solution of 43 mg (0.13 mmol) of (S)-1-[(3R,4S)-1-benzyl-4-(3-chloro-4-fluoro-phenyl)-pyrrolidin-3-yl]-ethanol in DMF (5 mL) was added NaH (9 mg, 0.18 mmol). The reaction mixture was stirred at RT for 30 minutes, and then at 50° C. for 20 minutes. A solution of 6-chloro-nicotinonitrile (22 mg, 0.16 mmol) in DMF (1 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, 1:3) yielded 48 mg (86%) of the title compound as a colorless oil. ES-MS m/e: 436.1 (M+H+).
