To a solution of 3-(6,7-dimethoxyquinazolin-4-ylthio)aniline (94 mg, 0.3 mmol), prepared as described in Example 115B, in THF (3 ml) was added DMAP (18 mg, 0.15 mmol) and phenyl 3-(2-cyanopropan-2-yl)phenylcarbamate (92 mg, 0.33 mmol) described in Example 278A. The reaction mixture was stirred at rt for 24 h. Concentration under reduced pressure gave a residue which was triturated with anhydrous diethyl ether to afford 1-(3-(2-cyanopropan-2-yl)phenyl)-3-(3-(6,7-dimethoxyquinazolin-4-ylthio)phenyl)urea (64.1 mg, 43%) as a solid. 1H NMR (300 MHz, DMSO-d6) δ 1.67 (s, 6H), 3.99 (s, 6H), 7.11 (d, J=6.6 Hz, 1H), 7.25 (d, J=7.5 Hz, 1H), 7.30-7.45 (m, 5H), 7.53 (d, J=8.1 Hz, 1H), 7.66 (s, 1H), 7.84 (s, 1H), 8.70 (s, 1H), 8.91 (d, J=6.6 Hz, 2H); LC-MS (ESI) m/z 500 (M+H)+.
