実験手順

To a solution of 1-(5-tert-butyl-isoxazol-3-yl)-3-(3-mercapto-phenyl)-urea (319 mg, 1.098 mmol) described in Example 44A in THF: DMF (2:1, 6 mL) was added NaH (95%, 30.5 mg, 1.207 mmol), stirred for 5-10 min at ambient temperature. Then 4-chloro-7-(2-chloro-ethoxy)-6-methoxy-quinazoline from Example 35A (300 mg, 1.098 mmol) was added as a solution in DMF:THF (2:1). The reaction mixture was then stirred overnight. Completion of the reaction was monitored by LCMS. The reaction mixture was diluted with ethyl acetate and washed the ethyl acetate layer with water and brine successively. The organic layer was dried (Na2SO4) concentrated to dryness to get the pure compound 1-(5-tert-Butyl-isoxazol-3-yl)-3-{3-[7-(2-chloro-ethoxy)-6-methoxy-quinazolin-4-ylsulfanyl]-phenyl}-urea (550 mg, 95%) as a white solid. 1H NMR (300 MHz, DMSO-d6) δ 9.60 (s, 1H), 9.05 (s, 1H), 8.68 (s, 1H), 7.85 (s, 1H), 7.55-7.25 (m, 5H), 6.45 (s, 1H), 4.50 (m, 2H), 4.05 (m, 5H), 1.25 (s, 9H); LC-MS (ESI) m/z 528 (M+H)+.
