Procedure

Using the procedure described in Example 306B, to a solution of 3-(6,7-dimethoxyquinazolin-4-ylthio)aniline (94 mg, 0.3 mmol), prepared as described in Example 115B, in THF (3.3 ml) was added DMAP (20 mg, 0.16 mmol) and phenyl 3-(1,1-difluoroethyl)-1-phenyl-1H-pyrazol-5-ylcarbamate (103 mg, 0.3 mmol), described in Example 318A. The crude was purified by silica gel chromatography (DCM/MeOH 0-15%) and triturated in diethyl ether to afford 1-(3-(1,1-difluoroethyl)-1-phenyl-1H-pyrazol-5-yl)-3-(3-(6,7-dimethoxyquinazolin-4-ylthio)phenyl)urea (127 mg, 75%) as a solid. 1HNMR (300 MHz, DMSO-d6) δ 1.99 (t, J=18 Hz, 3H), 3.99 (s, 6H), 6.67 (s, 1H), 7.25 (d, J=7.2 Hz, 1H), 7.34 (d, J=5 Hz, 2H), 7.38-7.59 (m, 7H), 7.77 (s, 1H), 8.66 (s, 1H), 8.68 (s, 1H), 9.27 (s, 1H); LC-MS (ESI) m/z 563 (M+H)+.
