実験手順

A mixture of 7-(2-bromoethoxy)-6-methoxy-4-(3'-methylanilino)quinazoline (0.25 g) and morpholine (4 ml) was stirred at ambient temperature for 4 hours. The mixture was evaporated and the residue was partitioned between methylene chloride and a dilute aqueous sodium bicarbonate solution. The organic phase was dried (MgSO4) and evaporated. The residue was triturated under diethyl ether to give 6-methoxy-4-(3'-methylanilino)-7-(2-morpholinoethoxy)quinazoline (0.198 g), m.p. 168°-170° C.
