Reaction Steps

16.4 g (0.05 mol) of 2-chloromethyl-3-(2-methoxycarbonyl-phenyl)-4H-quinazolin-4-one and 10 ml of liquid methylamine in 100 ml of ethylene glycol monomethyl ether are heated to 40° C. for 2 hours in an autoclave. After cooling the mixture, the colourless crystals are filtered off and washed several times with ethanol. 12 g (82.5% of theory) of 6-methyl-6,7-dihydro-5H,13H-quinazolino[3,2-a][1,4]benzodiazepine-5,13-dione are obtained.
