N-(Cyclohexylcarbonyl)piperazine (5.9 g., 0.03 mole) and 2-chloro-4-amino-6,7-dimethoxyquinazoline (7.2 g., 0.03 mole) are reacted according to the procedure of Example 127(a). The crude product crystallized from methanol affords analytically pure 4-amino-2-4-(cyclohexylcarbonyl)-1-piperazinyl]-6,7-dimethoxyquinazoline, m.p. 223°-225° C., resolidifying and remelting at 248.0°-250.0° C.
