الإجراء التجريبي

To tert-butyl 5-(2-(3-(2-methoxyacetamido)phenyl)quinazolin-4-ylamino)-1H-indazole-1-carboxylate (95 mg, 0.18 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. Product was purified using prep HPLC (method 25-50_70 mins) to afford 2-methoxyacetyl chloride N-(3-(4-(1H-indazol-5-ylamino)quinazolin-2-yl)phenyl)-2-methoxyacetamide. (45 mg, 59%)
