Procedure

To (3R)-tert-butyl 3-(2-(3-(4-(1H-indazol-5-ylamino)quinazolin-2-yl)phenoxy)acetamido)pyrrolidine-1-carboxylate was added a solution of 1:1 TFA:CH2Cl2 (3 mL) and stirred at RT for 2 h. The reaction mixture was concentrated in vacuo and the crude product was purified by prep HPLC (method 10-35—90 mins) to afford 2-(3-(4-(1H-indazol-5-ylamino)quinazolin-2-yl)phenoxy)-N—((R)-pyrrolidin-3-yl)acetamide.
