Reaction Steps

To tert-butyl 5-(2-(3-(2-(4-methylpiperazin-1-yl)acetamido)phenyl)-quinazolin-4-ylamino)-1H-indazole-1-carboxylate (22 mmol) was added a solution of 1:1 TFA:CH2Cl2 (2 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)-2-(4-methylpiperazin-1-yl)acetamide.
