실험 절차
Using the procedure described in Example 103B, tert-butyl 4-(4-{3-[3-(5-tert-butylisoxazol-3-yl)ureido]phenoxy}-6-methoxyquinazolin-7-yloxy)piperidine-1-carboxylate was reacted with 4.0 M HCl/1,4-dioxane at room temperature for 6 hours, to afford 1-(5-tert-butylisoxazol-3-yl)-3-{3-[6-methoxy-7-(piperidin-4-yloxy)quinazolin-4-yloxy]phenyl}urea as a crude product. LC-MS (ESI) m/z 533 (M+H)+.
