Versuchsvorschrift
To a mixture of 2,3,5-trimethyl-4(3H)-quinazolinone (1.1 g) and 4-(6-chloronicotinoyl)benzaldehyde (1.5 g) was added acetic anhydride (2 ml) and the mixture was stirred at 140° C for 2 hours. This reaction mixture was concentrated and the residue was washed with toluene-diethyl ether and dried to provide 1.4 g of yellow powder.
