Procedure
To a mixture of 2,3,5-trimethyl-4(3H)-quinazolinone (376 mg) and 4-(4-chlorobenzoyl)benzaldehyde (1.1 g) was added acetic anhydride (0.5 ml) and the mixture was stirred at 140° C. for 2 hours. This reaction mixture was concentrated and the residue was washed with diethyl ether and dried to provide 504 mg of yellow powder.
