실험 절차

A mixture of 33 mg (0.088 mmol) of (E)-5-(3,4-dichlorostyryl)-2,3-dihydro-1H-1,4-benzodiazepine-1-acetic acid, 30 mg (0.157 mmol) of 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride, 16 mg (0.105 mmol) of 1-hydroxybenzotriazole hydrate and 14 mg (0.187 mmol) of 2-methoxyethylamine was stirred in 3 ml of dichloromethane for 3 hours. The solution was washed with saturated sodium bicarbonate solution, dried over magnesium sulphate, filtered and evaporated to dryness. The residue was chromatographed three times on silica gel using dichloromethane/methanol (94:6), dichloromethane/methanol 92:8) and ethyl acetate/methanol (9:1) for the elutions. The product was dissolved in a solution of hydrogen chloride in ethyl acetate, evaporated to dryness and the residue triturated with diethyl ether. There was obtained 5 mg of (E)-5-(3,4-dichlorostyryl)-2,3-dihydro-N-(2-methoxyethyl)-1H-1,4-benzodiazepin-1-acetamide dihydrochloride as a red solid. MS: m/e 431.9 [M+H]+.
