실험 절차

8-Methoxy-4-(2-methylphenylamino)-2-chloroquinazoline (1.8 g, 0.006 mol) was dissolved in ethanolic ammonia and heated in a sealed vessel at 120° for 3 hours. After cooling, removal of excess solvent and chromatography (silica gel, 2% methanolic ammonia in chloroform) the 2 amino-4-(2-methylphenylamino)-8-methoxyquinazoline was isolated as crystals (0.52 g, 31%) from ethanol, m.p. 218°-220°.
