実験手順

A solution of 1-(5-tert-butylisoxazol-3-yl)-3-(3-(7-hydroxy-6-methoxyquinazolin-4-yloxy)phenyl)urea from Example 95B (50 mg, 0.111 mmol), (R)-3-hydroxy-1-tert-butoxycarbonylpyrrolidine (31 mg, 0.167 mmol), triphenylphosphine (44 mg, 0.167 mmol) and diisopropylazodicarboxylate (34 mg, 0.167 mmol) in dry tetrahydrofuran (1 mL) was stirred at room temperature for 15 h. The reaction mixture was partitioned between aqueous 1M sodium hydroxide solution (20 mL) and 10% methanol in dichloromethane (50 mL) and the organic layer was separated and washed with brine (50 mL), dried over MgSO4, and concentrated under reduced pressure. The residue was purified via silica gel chromatography eluting with 100% dichloromethane to 10% methanol in dichloromethane to afford (S)-tert-butyl 3-(4-(3-(3-(5-tert-butylisoxazol-3-yl)ureido)phenoxy)-6-methoxyquinazolin-7-yloxy)pyrrolidine-1-carboxylate as a colorless oil (35 mg, 51%). 1H NMR (300 MHz, CDCl3) δ 9.30 (brs, 1H), 8.62 (s, 1H), 8.30 (brs, 1H), 7.66 (s, 1H), 7.56 (s, 1H), 7.26-7.39 (m, 2H), 7.00 (m, 1H), 5.95 (s, 1H), 5.12 (s, 1H), 4.02 (s, 3H), 3.50-3.80 (m, 5H), 2.20-2.40 (m, 2H), 1.50 (s, 9H), 1.30 (s, 9H); LC-MS (ESI) m/z 619 (M+H)+.
