According to the procedure described in Example 138B, phenyl 3-tert-butyl-1-phenyl-1H-pyrazol-5-ylcarbamate (151 mg, 0.45 mmol) from Example 153A was reacted with 3-(6,7-dimethoxyquinazolin-4-ylthio)aniline from Example 115B (89 mg, 0.30 mmol). To this solution was added diisopropylethyl amine (80 μL, 0.45 mmol) and DMAP (4 mg, 0.03 mmol). After heating for 2 hours at 50° C., the reaction was concentrated to dryness. The resulting solid was triturated with 1:1 dichloromethane/hexane and the solid removed by filtration to afford the title compound (83 mg, 50% yield). 1H NMR (300 MHz, DMSO-d6) δ 9.24 (s, 1H), 8.68 (s, 1H), 8.47 (s, 1H), 7.55 (m, 4H), 7.40 (m, 5H), 7.20 (s, 1H), 6.95 (m, 1H), 6.36 (s, 1H), 3.98 (s, 6H), 1.25 (s, 9H); LCMS (ESI) m/z 555 (M+H)+.
