Reaction Steps

To 6.431 g of ethyl 6-chloro-7-nitro-1,2,4,5-tetrahydro-3H-3-benzazepine-3-carboxylate was added 120 ml of EtOH, followed by stirring at 60° C. for dissolution, and 12.15 g of reduced iron and 60 ml of 1 M hydrochloric acid were added thereto, followed by heating and refluxing for 1 hour. The reaction mixture was alkalified by the addition of a 1 M aqueous sodium hydroxide solution and then filtered through celite, and then the organic solvent was evaporated under reduced pressure. The residue was extracted with chloroform, the organic layer was dried over anhydrous sodium sulfate and then filtered, and the filtrate was concentrated under reduced pressure to obtain 5.743 g of ethyl 7-amino-6-chloro-1,2,4,5-tetrahydro-3H-3-benzazepine-3-carboxylate as a reddish orange viscous substance.
