实验过程

To tert-butyl 5-(2-(3-(2-methoxy-2-oxoacetamido)phenyl)quinazolin-4-ylamino)-1H-indazole-1-carboxylate (18 mg, 0.033 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 residue was triturated with ethyl ether to get a yellow solid to afford methyl 2-(3-(4-(1H-indazol-5-ylamino)quinazolin-2-yl)phenylamino)-2-oxoacetate. (15 mg, 100%).
