실험 절차

To a solution of 3.06 ml (40.1 mmol) of thiophosgene in 100 ml of dichloromethane were slowly added a solution of 10 g (36.5 mmol) of 6,7-dimethoxy-4-(1-piperazinyl)quinazoline obtained by the method described in South African Patent No. 67 06512 (1968) in 100 ml of dichloromethane and 12.4 ml (89.1 mmol) of triethylamine under ice-cooling. The resulting mixture was stirred at the same temperature in an atmosphere of argon for 2 hours. After the solvent was evaporated, the residue was purified by silica gel chromatography to give 6.65 g (52%) of the desired compound.
