実験手順

0.60 ml (3.8 mmol) of diethyl cyanophosphate and 0.90 ml (6.4 mmol) of triethylamine were dropped, in this order, into a solution of 0.50 g (1.4 mmol) of 2-carboxy-4-(3,4-methylenedioxybenzyl)amino-6-chloroquinazoline and 0.28 g (1.9 mmol) of sodium 2-aminoethanesulfonate in 15 ml of dimethylformamide under cooling with ice and stirring. The obtained mixture was stirred at room temperature for several days, followed by the addition of 10 ml of 1N hydrochloric acid and water. The crystals thus precipitated were recovered by filtration, washed with water and air-dried to give 0.61 g of the title compound.
