N-bromobutanimide → HCID 58495360, compound

Participants

Reaction Steps

To a solution of 5.74 g of ethyl 7-amino-6-chloro-1,2,4,5-tetrahydro-3H-3-benzazepine-3-carboxylate in 100 ml of dichloromethane was added portionwise 3.9 g of N-bromosuccinimide under ice-cooling, followed by stirring for 40 minutes. The reaction mixture was concentrated under reduced pressure and the residue was purified by silica gel chromatography (elution solvent: HEX-EtOAc) to obtain 5.769 g of ethyl 7-amino-8-bromo-6-chloro-1,2,4,5-tetrahydro-3H-3-benzazepine-3-carboxylate as a brown solid.
