3,5-Dichlorobenzoyl chloride → 3,5-Dichloro-N-(7,8-dimethoxy-1-phenoxy-2,3,4,5-tetrahydro-1H-3-benzazepin-3-yl)benzamide

참여 물질

반응 단계

3,5-Dichlorobenzoyl chloride (1.7 g) was added to a solution of 3-amino-7,8-dimethoxy-1-phenoxy-2,3,4,5-tetrahydro-3-benzazepine (2.1 g) in 100 ml dichloromethane containing sodium bicarbonate (3 g). After one hour, the mixture was filtered and concentrated. The solid residue was eluted through silica with 10% ethyl acetate in dichloromethane to yield 2.4 g of light tan solid, mp 182°-184°. This solid was recrystallized from acetonitrile to yield 2 g of white crystals, mp 184°-185°.
