Procedure

Prepared according to Procedure C using (4-Benzyloxy-3-trifluoromethylphenyl)-(6-(5-(1,3-dioxolan-2-yl)-furan-2-yl)-quinazolin-4-yl)-amine (470 mg, 0.88 mmol) solution in THF (5 ml) followed by the addition of 2N HCl (20 ml) at room temperature. The resulting mixture was stirred for 30 minutes. Water was added (15 ml) then filtered. The yellow solid was washed with water and small amount of ether and dried in vacuo (0.39 g, 84% yield). ESI-MS m/z 490 (M+H)+.
