Procedure

TFA (3 mL) was added drop wise to a suspension of (3-{4-[3-Chloro-4-(pyridin-2-ylmethoxy)-phenylamino]-7-methoxy-quinazolin-6-yloxy}-propyl)-carbamic acid tert-butyl ester (0.9 g, 1.59 mmol) in DCM (3 mL). Stir for 1 hour and the reaction mixture was diluted with DCM (20 ml) and sat. NaHCO3 (20 mL). Phases were separated and organic layer was extracted with DCM (20 mL). Organic layers were combined, dried (Na2SO4), and concentrated to give 0.7 g (95%) of desired product.
