5-Bromo-2-iodobenzamide

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To 5-bromo-2-iodobenzoic acid (20 g, 61.2 mmol) in 1:1 mixture of dichloromethane and dimethylformamide (200 mL) was added HATU (25 g, 65.8 mmol), and the solution stirred 2 min. Excess ammonium chloride (20 g) was added, and the heterogeneous mixture was stirred 1 h. Ammonium hydroxide (20 mL) was added causing a white precipitate. The precipitate was filtered and washed with ethyl acetate. The solution was diluted with ethyl acetate, washed with water, 1 N hydrochloric acid, saturated sodium bicarbonate, and saturated sodium chloride, dried (magnesium sulfate), filtered, and concentrated under reduced pressure resulting in the formation of a white precipitate. The solid was filtered to provide the title compound (14.4 g). ESI MS m/z 327.0 [M+H]+. the heterogeneous mixture was stirred 1 h The precipitate was filtered washed with ethyl acetate The solution was diluted with ethyl acetate washed with water, 1 N hydrochloric acid, saturated sodium bicarbonate, and saturated sodium chloride dried (magnesium sulfate) filtered concentrated under reduced pressure resulting in the formation of a white precipitate The solid was filtered
