실험 절차
8-methoxy-4-(2-methylphenylamino)-2-chloroquinazoline (1.00 g, 0.0033 mol) was dissolved in ethanol (15 ml) with o-toluidine (1.06 g, 0.0099 mol) and heated in a sealed vessel at 150° for 5 hours. After cooling and removal of excess solvent in vacuo the solid was chromatographed (silica gel, chloroform). 8-Methoxy-2,4-bis(2-methylphenylamino)quinazoline was isolated as crystals (0.93 g, from ethanol/water, m.p. 185°-187°.
