(6-氨基-3-溴-2-氟苯基)甲醇

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A suspension mixture of (6-amino-3-bromo-2-fluorophenyl)methanol (8.3 g, 37.72 mmol) and manganese(IV) oxide (19.68 g, 226.32 mmol) in dichloromethane (400 mL) was stirred at room temperature overnight. The solid was filtered off, and the filtrate was concentrated to give the title product as a light yellow solid (6.0 g, 73%), which was directly used in the next step without further purification. MS (ES+) C7H5BrFNO requires: 217, found: 218, 220 [M+H]+. The solid was filtered off the filtrate was concentrated

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a solution of 6-amino-3-bromo-2-fluorobenzoic acid (9.0 g, 38.46 mmol) in THF (150 mL) was added BH3-THF (1 M, 193 mL) at 0° C., and the mixture was stirred at room temperature overnight. The reaction was slowly quenched with methanol (50 mL), and the solvents were removed under reduced pressure. The residue was diluted with 200 mL of ethyl acetate, washed with water (200 mL) and brine (200 mL), dried over sodium sulfate, filtered and concentrated to afford the title product (8.3 g, 98%), which was directly used in the next step without further purification. MS (ES+) C7H7BrFNO requires: 219, found: 220, 222 [M+H]+. The reaction was slowly quenched with methanol (50 mL) the solvents were removed under reduced pressure The residue was diluted with 200 mL of ethyl acetate washed with water (200 mL) and brine (200 mL) dried over sodium sulfate filtered concentrated
