1-(5-Tert-butylisoxazol-3-yl)-3-(3-hydroxyphenyl)urea → 1-(5-Tert-butylisoxazol-3-yl)-3-(3-(6-(2-methoxyethoxy)quinazolin-4-yloxy)phenyl)urea

Participants

Reaction Steps

The title compound was prepared from 1-(5-tert-butylisoxazol-3-yl)-3-(3-hydroxyphenyl)urea from Example 1A (138 mg, 0.5 mmol) and 4-chloro-6-(2-methoxyethoxy)quinazoline from Example 40A Step 5 (119 mg, 0.5 mmol) using the procedure of Example 16C. The crude product was purified by column chromatography (25-100% EtOAc/hexanes) to give 1-(5-tert-butylisoxazol-3-yl)-3-(3-(6-(2-methoxyethoxy)quinazolin-4-yloxy)phenyl)urea (45 mg, 0.094 mmol, 20%). 1H NMR (300 MHz, DMSO-d6) δ 9.59 (s, 1H), 9.01 (s, 1H), 8.62 (s, 1H), 7.94 (d, 1H), 7.74-7.64 (m, 3H), 7.60 (s, 1H), 7.42 (t, 1H), 7.27 (d, 1H), 6.99 (d, 1H), 6.48 (s, 1H), 4.37-4.31 (m, 2H), 3.78-3.71 (m, 2H), 3.34 (s, 3H), 1.28 (s, 9H); LC-MS (ESI) m/z 478 (M+H)+.
