To a stirred solution of 2.85 g. (0.01 mole) of 7-chloro-2-hydrazino-5-phenyl-3H-1,4-benzodiazepine in 100 ml. of methanol is added 2.24 g. (0.01 mole) of 5-(diethylamino)-2-oxo-valeric acid, hydrochloride [prepared by the method of Libman and Kutznetsov J. Gen. Chem. (USSR), 33, 1938 (1963)]. The mixture is kept under nitrogen at ambient temperature for 2 hours and then concentrated in vacuo. The residue is mixed with aqueous sodium bicarbonate and extracted with methylene chloride. The extract was washed with brine, dried over anhydrous magnesium sulfate and concentrated in vacuo. The residue of 7-chloro-2-[[1-carboxy-4-(diethylamino)-butylidene]hydrazino]-5-phenyl-3H-1,4-benzodiazepine is used without further purification.
