실험 절차

Potassium carbonate (414 mg, 3 mmol) was added to a suspension of 4-(4-bromo-2-fluoroanilino)-7-hydroxy-6-methoxyquinazoline (546 mg, 1.5 mmol) in DMF (5 ml). After stirring for 10 minutes at ambient temperature, 1-(tert-butoxycarbonyl)-4-(4-methylphenylsulphonyloxymethyl)piperidine (636 mg, 1.72 mmol) was added and the mixture was heated at 95° C. for 2 hours. After cooling, the mixture was poured onto cooled water (20 ml). The precipitate was collected by filtration, washed with water, and dried under vacuum to give 4-(4-bromo-2-fluoroanilino)-7-(1-(tert-butoxycarbonyl)piperidin-4-ylmethoxy)-6-methoxyquinazoline (665 mg, 79%).
