Sodium borohydride → (5-Bromo-2-(2-methylpiperidin-1-YL)phenyl)methanol

참여 물질

반응 단계

To a solution of 5-bromo-2-(2-methylpiperidin-1-yl)benzaldehyde (16.30 g; 57.76 mmol) in MeOH (300 mL) was added sodium borohydride (2.19 g; 57.76 mmol) at 5° C. in a portion-wise fashion and stirred for 30 min. After this time, reaction mixture was diluted with a saturated aqueous solution of NH4Cl (300 mL), extracted with EtOAc. The org layers were washed with aqueous solution of NH4Cl (150 mL), brine (300 mL), dried over MgSO4 and evaporated under vacuum to give the title compound as a yellow oil (15.9 g, 97%). LC/MS (Method A): 285.6 (M+H)+. HPLC (Method A): Rt 2.13 min (Purity: 94.9%).
