Procedure

3-Aminothiophenol (1.42 mL, 13.3 mmol) and 4-chloro-6,7-dimethoxyquinazoline (3.0 g, 13.3 mmol) were reacted using the procedure described in Example 46 to give 3-(6,7-dimethoxyquinazolin-4-ylthio)aniline (4.32 g, 13.8 mmol, 100% (wet with H2O)). 1H NMR (300 MHz, DMSO-d6) δ 8.70 (s, 1H), 7.33 (s, 1H), 7.31 (s, 1H), 7.13 (t, 1H), 6.80 (s, 1H), 6.73 (d, 1H), 6.68 (d, 1H), 5.34 (br s, 2H), 3.98 (s, 3H), 3.97 (s, 3H); LC-MS (ESI) m/z 314 (M+H)+.
