反应详情

A mixture of 0.200 g of 1,2,3,4-tetrahydro-1-(4-nitrobenzoyl)-5H-1-benzazepin-5-one in 2.5 ml of acetic acid is warmed until solution then allowed to cool to room temperature. While stirring, a solution of 0.103 g of bromine in 0.5 ml of acetic acid is added dropwise. After rapid decolorization, the reaction mixture is stirred for 1.5 hours and poured into water. The solid is collected, washed with water and air dried to give 220 mg of the desired product as a crystalline solid, Mass Spectrum; MH+ =389,391.
