실험 절차

A stirred solution of phenyl 3-tert-butyl-1-isobutyl-1H-pyrazol-5-ylcarbamate described in Example 332A (150 mg, 0.47 mmol), N,N-diisopropylethylamine (80 mg, 0.62 mmol) and 3-(6,7-dimethoxyquinazolin-4-ylthio)aniline (prepared as described in Example 115B) (100 mg, 0.31 mmol) in THF (1.0 mL) was heated at 60° C. for 15 h. After cooling to rt, the reaction solution was partitioned between dichloromethane and a saturated aqueous solution of sodium carbonate. The organic phase was separated and concentrated under reduced pressure. The crude product was purified via silica gel column chromatography (eluting with a gradient of 40:1 to 20:1 dichloromethane:methanol) then reverse-phase preparative HPLC to afford 1-(3-tert-butyl-1-isobutyl-1H-pyrazol-5-yl)-3-(3-(6,7-dimethoxyquinazolin-4-ylthio)phenyl)urea (52 mg, 32%) as a pale yellow solid. 1H NMR (400 MHz, DMSO-d6) δ 9.07 (s, 1H), 8.70 (s, 1H), 8.48 (s, 1H), 7.85 (s, 1H), 7.24-7.53 (m, 5H), 6.07 (s, 1H), 4.00 (s, 6H), 3.72 (d, J=7.2 Hz, 2H), 2.07 (m, 1H), 1.20 (s, 9H), 0.83 (d, J=6.8 Hz, 6H); LC-MS (ESI) m/z 535 (M+H)+.
