Versuchsvorschrift

0.129 g of ethyl acetoimidate hydrochloride was added to 15 ml of a suspension of 0.5 g of 5-(2-amino-ethoxy)-7-chloro-1-[2-methoxy-4-(2-chlorobenzoylamino)-benzoyl]-2,3,4,5-tetrahydro-1H-benzoazepine in ethanol with ice-cooling. The mixture was stirred overnight at room temperature. Then, 0.163 g of ethyl acetoimidate hydrochloride was further added. The mixture was stirred at 50° C. for 7 hours and then refluxed for 3 hours. After cooling, the reaction mixture was subjected to filtration to remove insolubles. The filtrate was concentrated. The residue was purified by silica gel column chromatography (elutant: dichloromethane/methanol=30/1) to obtain 0.2 g of 5-[2-(1-iminoethyl)aminoethoxy]-7-chloro-1-[2-methoxy-4-(2-chlorobenzoylamino)benzoyl]-2,3,4,5-tetrahydro-1H-benzo-azepine hydrochloride.
