Versuchsvorschrift

To a solution of 2-carbobenzoxyaminomethyl-3-amino-4-hydroxy-4-(2-chlorophenyl)-6-chloro-3,4-dihydroquinazoline (2.36 g) in dimethylformamide (15 ml), acetyl chloride (0.79 g) is added, and the resultant mixture is stirred at room temperature for 5 hours and allowed to stand overnight. The reaction mixture is neutralized with aqueous sodium bicarbonate and shaken with ethyl acetate. The organic layer is washed with water and evaporated to give 2-carbobenzoxyaminomethyl-3-acetamido-4-hydroxy-4-(2-chlorophenyl)-6-chloro-3,4-dihydroquinazoline (2.1 g).
