Versuchsvorschrift

In 30 ml of a 1:1 mixture of tetrahydrofuran and methanol were dissolved 0.30 g of 5-ethoxycarbonylmethylidene-7-chloro-1-[2-methyl-4-(2-methylbenzoylamino)-benzoyl]-2,3,4,5-tetrahydro-1H-benzoazepine and 0.55 g of nickel chloride hexahydrate. Thereto was slowly added 0.26 g of sodium borohydride with ice-cooling and stirring. The mixture was stirred for 10 minutes with ice-cooling. The resulting insolubles were removed by filtration with Celite. The filtrate was concentrated. The residue was purified by silica gel column chromatography (elutant: ethyl acetate/n-hexane=1/1) to obtain 0.13 g of 5-ethoxycarbonylmethyl-7-chloro-1-[2-methyl-4-(2-methylbenzoylamino)benzoyl]-2,3,4,5-tetrahydro-1H-benzoazepine.
