反应详情

4-(4-fluoro-2-methyl-1H-indol-5-yloxy)-7-(benzyloxy)-6-methoxyquinazoline (Compound 2, 0.46 g, 1.1 mmol) was dissolved in N,N-dimethylformamide (10 mL). Palladium hydroxide catalyst (250 mg, 10% on carbon) was added, followed by ammonium formate (0.67 g, 10.6 mmol). The reaction solution was stirred for 2 hours at room temperature. The catalyst was filtered through a CELITE pad, then the solution was evaporated, then dried in high vacuum overnight to generate Compound 3 as a brown solid (0.36 g, 100%) m/z: 340 (M+H, 100%) (positive ionization mode).
