実験手順
To a suspension of tert-butyl 5-(7-methoxy-6-(2-methoxyethoxy)-2-(3-(2-morpholinoacetamido)phenyl)quinazolin-4-ylamino)-1H-indazole-1-carboxylate. (0.321 g, 0.47 mmol) in CH2Cl2 (3 mL) was added TFA (3 mL). The resulting mixture was stirred at RT for 1.5 h, upon which it was concentrated in vacuo and the residue purified by preparative HPLC (10-35-90 method) to give N-(3-(4-(1H-indazol-5-ylamino)-7-methoxy-6-(2-methoxyethoxy)quinazolin-2-yl)phenyl)-2-morpholinoacetamide trifluoroacetate salt (0.141 g, 0.202 mmol, 43% over two steps). MS 584 (M+1). HPLC retention time 4.40 mins.
