Reaction Steps

Following the procedure described in Example 138B with 3-fluoro-4-(trifluoromethyl)phenylcarbamate as described in Example 150 (135 mg, 0.45 mmol) and using 3-(6,7-dimethoxyquinazolin-4-ylthio)aniline from Example 115B (94 mg, 0.3 mmol). To this mixture diisopropylethyl amine (58 mg, 0.45 mmol) and DMAP (3.7 mg, 0.03 mmol) the reaction was heated at 50° C. overnight. The reaction was concentrated to dryness and triturated with dichloromethane. The resulting solid was collected by vacuum filtration to give 156 mg. 1H NMR (300 MHz, DMSO-d6) δ 9.45 (s, 1H), 9.10 (s, 1H), 8.79 (s, 1H), 7.8 (s, 1H), 7.6 (m, 2H), 7.5 (m, 1H), 7.35 (m, H), 7.25 (m, 4H), 4.00 (s, 6H). LCMS (ESI) m/z 519 (M+H)
