To a solution of 1-(pyridin-3-yl)propan-1-one (2.46 g, 18.20 mmol, purchased from Lancaster Synthesis Ltd.) in MeOH (15 mL) at rt under N2 atmosphere was added sodium borohydride powder (0.690 g, 18.20 mmol). After stirring at rt for 1.5 hr, to the reaction solution was added water (20 ml). The resulting mixture was stirred for 4 min, extracted with EtOAc (20 mL×3). The organic layers were combined, washed with water, sat. aq. NaCl solution and dried over MgSO4. Removal of the solvents provided the crude title compound as white solid. Mass Spectrum (ESI) m/z=138.0 (M+1).
