실험 절차

To a solution of 2-carbobenzoxyaminomethyl-3-amino-4-hydroxy-4-(2-chlorophenyl)-6-chloro-3,4-dihydroquinazoline (18.84 g) in dimethylformamide (100 ml), chloroacetyl chloride (8.48 g) is added, and the resultant mixture is stirred at room temperature for 1 hour and allowed to stand overnight. The reaction mixture is neutralized with aqueous sodium bicarbonate and shaken with ethyl acetate. The ethyl acetate layer is evaporated under reduced pressure to remove the solvent, and the residue is washed with ether to give 2-carbobenzoxyaminomethyl-3-(2-chloroacetamido)-4-hydroxy-4-(2-chlorophenyl)-6-chloro-3,4-dihydroquinazoline (18.9 g). This product is recrystallized from ethyl acetate to give crystals melting at 130° to 134° C.
