100 mg of 9-iodo-8-methyl-5-phenyl-11H-1,3-dioxolo[4,5-h]imidazo[1,2-c][2,3]benzodiazepine is stirred in 2 ml of dimethylformamide, 0.03 ml of triethylamine, 0.032 ml (30 mg) of diethyl phosphite and 15 mg of tetrakis(triphenylphosphine)-palladium(O) at 100° C. for 2 hours. Then, it is diluted with 10 ml of water and extracted with ethyl acetate. The organic phase that is concentrated by evaporation is chromatographed on silica gel with dichloromethane:ethanol=95:5 as an eluant. 10 mg of 8-methyl-5-phenyl-11H-1,3-dioxolo[4,5-h]imidazo[1,2-c][2,3]benzodiazepine-9-phosphonic acid diethyl ester is obtained.
