To tert-butyl 5-(2-(3-(3-(4-isopropylpiperazin-1-yl)propanamido)phenyl)-quinazolin-4-ylamino)-1H-indazole-1-carboxylate (60 mg, 0.094 mmol) was added a solution of 1:1 TFA:CH2Cl2 (4 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 N-(3-(4-(1H-indazol-5-ylamino)quinazolin-2-yl)phenyl)-3-(4-isopropylpiperazin-1-yl)propanamide. (61 mg, 0.11 mmol, 100%).
