Procedure

A stirred mixture of phenyl 3-cyclopropyl-1-phenyl-1H-pyrazol-5-ylcarbamate as described in Example 353A (250 mg, 0.78 mmol) and 3-(6,7-dimethoxyquinazolin-4-ylthio)aniline (prepared as described in Example 115B) (200 mg, 0.64 mmol) in DMSO (1 mL) was heated to 40° C. for 48 h. After cooling to rt, water (20 mL) was added. The resulting suspension was filtered and the collected solid purified via preparative silica gel thin-layer chromatography (eluting with a mixture of 10:10:1 ethyl acetate: dichloromethane: methanol) to give a solid which was triturated with diethyl ether (50 mL) to afford 1-(3-cyclopropyl-1-phenyl-1H-pyrazol-5-yl)-3-(3-(6,7-dimethoxyquinazolin-4-ylthio)phenyl)urea (162 mg, 47%) as a colorless solid. 1H NMR (400 MHz, DMSO-d6) δ9.21 (s, 1H), 8.68 (s, 1H), 8.49 (s, 1H), 7.77 (s, 1H), 7.22-7.51 (m, 10H), 6.15 (s, 1H), 3.99 (s, 6H), 1.86 (m, 1H), 0.85-0.91 (m, 2H), 0.65-0.68 (m, 2H); LC-MS (ESI) m/z 539 (M+H)+.
