実験手順

Step N5. To 3-chloro-5-(hydroxymethyl)benzamide (0.7 g, 3.77 mmol) in THF (20 mL) was added borane-dimethylsulfide complex (0.9 g, 11.8 mmol) slowly. The mixture was refluxed for 20 hours. Excess borane reagent was quenched with methanol and solvent was removed by rotovap. The resulting residue was purified by column with dichloromethane/methanol (1:1) as the eluant. 3-chloro-5-(hydroxymethyl)benzylamine was obtained in white solid (240 mg, 37%). 1H NMR (300 MHz, CD3OD): δ 3.81 (s, 2H), 4.61 (s, 2H), 7.25 (s, 1H), 7.28(s, 1H), 7.59, 7.30(s, 1H). MH+=172.08.
