실험 절차

To a solution of 2-phthalimidoacetyl chloride (1.5 g) in benzene (20 ml) and dimethylformamide (10 ml), 5-chloro-2-(3-aminomethyl-5-methyl-4H-1,2,4-triazol-4-yl)-benzophenone dihydrobromide (2.3 g) is added under ice cooling and stirring, and the temperature within the flask is gradually returned to room temperature. The reaction mixture is allowed to stand at room temperature, neutralized with saturated aqueous sodium bicarbonate, and shaken with ethyl acetate. The precipitated crystals are filtered, washed with methanol and dried to give 5-chloro-2-[3-(2-phthalimidoacetamidomethyl)-5-methyl-4H-1,2,4-triazol-4-yl]-benzophenone (1.68 g) as crystals melting at 251°-253° C.
