Using an analogous procedure to that described in Example 34, 6-bromomethyl-4-(3-methylanilino)quinazoline was reacted with 2-mercapto-1-methylimidazole sodium salt [prepared by the reaction of 2-mercapto-1-methylimidazole and sodium ethoxide in ethanol] to give 4-(3-methylanilino)-6-(N-methylimidazol-2-ylthiomethyl)quinazoline in 65% yield, m.p. 137-139° C.; NMR Spectrum: 2.42 (s, 3H), 3.6 (s, 3H), 4.48 (s, 2H), 6.97 (d, 1H), 7.13 (d, 1H), 7.39 (t, 1H), 7.55 (m, 2H), 7.6 (d, 1H), 7.83 (d, 1H), 7.93 (m, 1H), 8.5 (s, 1H), 8.83 (s, 1H), 10.9 (broad s, 1H); Elemental Analysis: Found C, 48.3; H, 3.6; N, 11.6; C20H19N5S 2CF3CO2H 0.5H2O requires C, 48.1; H, 3.5; N, 11.7%.
