Procedure
N-(3-cyclohexenylcarbonyl)piperazine (7.65 g., 0.04 mole) and 2-chloro-4-amino-6,7-dimethoxyquinazoline (9.6 g., 0.04 mole) are reacted according to the procedure of Example 1(a). The crude product crystallized from methanol affords analytically pure 4-amino-2-[4-(3-cyclohexenylcarbonyl)-1-piperazinyl]-6,7-dimethoxyquinazoline, m.p. 211°-213° C. resolidifying and melting at 234.0° -236.0°C.
