Procedure

To a solution of 2-(3-(4-(1H-indazol-5-ylamino)quinazolin-2-yl)phenoxy)acetic acid (80 mg, 0.16 mmol) in dry CH2Cl2:DMF (2.0:0.1 mL), added DIEA (29 μL, 0.16 mmol) and PyBOP® (46 mg, 0.088 mmol). After stirring the mixture at RT for 15 minutes, dimethylamine was bubbled through the solution for 15 minutes. Added another 1.0 equivalent of DIEA and 0.55 equivalents of PyBOP® after stirring the solution for 15 minutes, followed by dimethylamine bubbling for an additional 15 minutes. The solvent was removed in vacuo and the crude material was purified by prep HPLC (method 20-45—90 mins) to afford 2-(3-(4-(1H-indazol-5-ylamino)quinazolin-2-yl)phenoxy)-N,N-dimethylacetamide (26 mg, 0.059 mmol, 37%).
