実験手順

To a solution of 4-(3-aminophenoxy)-7-methoxyquinazolin-6-ol (2.0 g, ˜0.0070 mol) in DMF (10 mL), phenyl 5-tert-butylisoxazol-3-ylcarbamate (1.74 g, 0.0067 mol) was added. The reaction mixture was stirred at 60° C., overnight. The solvent was evaporated under vacuum and the residue was sonicated in the presence of ethyl ether (60 mL). The solid was filtered and washed with ethyl ether to afford 1-(5-tert-butylisoxazol-3-yl)-3-(3-(6-hydroxy-7-methoxyquinazolin-4-yloxy)phenyl)urea (2.75 g, 87.5% yield). 1HNMR (DMSO-d6): δ 10.53 (s, 1H), 9.57 (s, 1H), 8.99 (s, 1H), 8.50 (s, 1H), 7.52 (d, 2H), 7.37 (m, 2H), 7.25 (d, 1H), 6.95 (d, 1H), 6.18 (s, 1H), 4.00 (s, 3H), 1.30 (s, 9H); LC-MS (ESI) m/z 450 (M+H)+.
