To tert-butyl 5-(2-(3-(2-(2-(dimethylamino)ethylamino)-2-oxoethoxy)-phenyl)quinazolin-4-ylamino)-1H-indazole-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 20-45_90 mins) to afford N-(1H-indazol-5-yl)-2-(3-(oxazol-2-ylmethoxy)phenyl)quinazolin-4-amine. (12 mg, 0.028 mmol).
