Procedure
(S)-3-(5-(1-Methylpyrrolidin-2-yl)pyridin-3-yl)acrylonitrile (preparation 2) (185 mg, 0.87 mmol) and 5% Pd/C (50 mg) in MeOH (5 mL) were stirred under an atmosphere of hydrogen for 72 hours. The reaction mixture was filtered through Celite then the solvent evaporated. The crude product was purified by flash chromatography (5% [20% ammonia in MeOH] in DCM) to give the title compound as a pale yellow oil (141 mg, 75%).
