80.3 gm (0.247 mol) of 2-(4-acetoxy-phenyl)-3-methyl-6-methoxy-3,4-dihydro-quinazolin-4-one were suspended in 800 ml of concentrated aqueous ammonia, and the suspension was heated for 1.5 hours on a steam bath, whereby at first a clear solution was obtained, and after about 60 minutes the formation of a white precipitate began. After cooling to 0° C., the product was suction-filtered off, washed with water and dried at 80° C. in a circulating air drier.
