Procedure

Using the procedure described in Example 159B, phenyl 3-(1,3-difluoro-2-methylpropan-2-yl)-1-phenyl-1H-pyrazol-5-ylcarbamate described in Example 167B (0.186 g, 0.5 mmol), 3-(6-methoxy-7-(2-methoxyethoxy)quinazolin-4-ylthio)aniline described in Example 231A (0.143 g, 0.4 mmol), and N,N-diisopropylethylamine (0.8 mL) in THF (6 mL) at 50° C. for 6 hours, which was purified by silica gel chromatography with EtOAc/hexane as eluants and preparative HPLC (C18 column and 55-70% MeCN/H2O with 0.05% AcOH) to afford 1-[3-(1,3-difluoro-2-methylpropan-2-yl)-1-phenyl-1H-pyrazol-5-yl]-3-{3-[6-methoxy-7-(2-methoxyethoxy)quinazolin-4-ylthio]phenyl}urea as solid (0.072 g, 28%). 1H NMR (300 MHz, DMSO-d6) δ 9.27 (s, 1H), 8.68 (s, 1H), 8.56 (s, 1H), 7.80 (s, 1H), 7.56 (m, 4H), 7.33-7.47 (m, 5H), 7.24 (d, 1H), 6.51 (s, 1H), 4.71 (m, 2H), 4.55 (m, 2H), 4.33 (m, 2H), 3.99 (s, 3H), 3.77 (m, 2H), 3.34 (s, 3H), 1.31 (s, 3H); LC-MS (ESI) m/z 635 (M+H)+.
