실험 절차
A solution of tert-butyl 5-(2-(3-(2-(isopropylamino)-2-oxoethoxy)phenyl)-quinazolin-4-ylamino)-1H-indazole-1-carboxylate (4.30 g, 7.79 mmole) in TFA (20 mL) and CH2Cl2 (20 mL) was stirred at room temperature for 1 h. The reaction mixture was concentrated in vacuo, and to the crude residue was added ca. 50 mL Et2O. The resulting bright yellow suspension was stirred for 15 minutes and filtered and dried giving 2-(3-(4-(1H-indazol-5-ylamino)quinazolin-2-yl)phenoxy)-N-isopropylacetamide trifluroacetate salt. (4.1 g, mmol, %).
