실험 절차

To a solution of (1-(5-tert-butyl-isoxazol-3-yl)-3-(3-mercapto-phenyl)-urea described in Example 44A (303.02 mg, 1.04 mmol) in THF: DMF (2:1, 6 mL) was added NaH (95%, 28.9 mg, 1.144 mmol), stirred for 5-10 min at ambient temperature. Then (4-chloro-7-(3-chloro-propoxy)-6-methoxy-quinazoline, (300 mg, 1.04 mmol) described in Example 27A was added as 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 afford the pure 1-(5-tert-butyl-isoxazol-3-yl)-3-{3-[7-(3-chloro-propoxy)-6-methoxy-quinazolin-4-ylsulfanyl]-phenyl}-urea (480 mg, 85%) 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), 7.60-7.28 (m, 5H), 6.50 (s, 1H), 4.35 (t, 2H), 4.05 (s, 3H), 3.82 (t, 2H), 1.30 (s, 9H); LC-MS (ESI) m/z 542 (M+H)+.
