Reaction Steps
A 70% aqueous ethylamine solution (40 ml) was added to a solution (70 ml) of 7-chloro-6-nitro-4(3H)-quinazolone (6.31 g, 28.0 mmol) in ethanol and the mixture was heated with stirring at 110° C. for 4 hours in a sealed tube. After cooling to room temperature, the reaction mixture was poured into water and the precipitated crystals were collected by filtration. The crystals were washed with ethanol and dried to give the title compound (2.6 g, 39%).
