Sodium borohydride → (5-Bromopyridin-2-yl)methanol

참여 물질

반응 단계

To a solution of 5-bromopyridine-2-carbaldehyde (300 mg) in methanol (10 mL) was added sodium borohydride (61 mg) and the reaction stirred at room temperature for 72 h. The reaction was quenched with saturated aqueous sodium carbonate solution (20 mL) and water (20 mL) and extracted into dichloromethane (3×30 mL). The organic layers were dried (MgSO4) and reduced in vacuo to give (5-bromo-pyridin-2-yl)-methanol as a white solid.
