Trifluoroacetic acid → (2R)-N-(3-(4-(1H-indazol-5-ylamino)quinazolin-2-yl)phenyl)pyrrolidine-2-carboxamide

Participants

Reaction Steps

To tert-butyl 5-(2-(3-((R)-pyrrolidine-2-carboxamido)phenyl)quinazolin-4-ylamino)-1H-indazole-1-carboxylate (65 mg, 0.12 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 (2R)—N-(3-(4-(1H-indazol-5-ylamino)quinazolin-2-yl)phenyl)pyrrolidine-2-carboxamide. (64 mg, 100%).
