Borohydride → (2-Amino-5-bromo-4-chlorophenyl)methanol

참여 물질

반응 단계

To a solution of 2-amino-5-bromo-4-chlorobenzoic acid (9.0 g, 36.0 mmol) in THF (150 mL) was added borohydride in THF (144 mL, 1 M) at room temperature, and the reaction mixture was stirred overnight. The reaction mixture was quenched with methanol (50 mL), and concentrated to a volume of 50 mL. The residue was diluted with water (100 mL) and extracted with ethyl acetate (150 mL×3). The organic layers were separated, combined, washed with water (100 mL) and brine (100 mL), dried over sodium sulfate, filtered and concentrated to afford the title compound (crude, 6 g, 71%).
