(R)-1-Benzyl-3-mesyloxypyrrolidine (5.0 g, 20 mmol) was dissolved in acetonitrile (6 mL) and tetrabutylammonium cyanide (11.1 g, 41.4 mmol) was added. The mixture was heated at 65° C. for 3 hours and then cooled to room temperature and extracted with ethyl ether (100 mL). The organic layer was washed with saturated NaHCO3 (2×50 mL), dried over MgSO4, and concentrated under reduced pressure to give (S)-1-benzyl-3-cyanopyrrolidine (3.1 g, 85%) as a yellow oil: VPC: 100%;
