Procedure

To a solution of (2S,4R)-tert-butyl 2-(((1R,2S)-1-((cyclopropylsulfonyl)carbamoyl)-2-vinylcyclopropyl)carbamoyl)-4-((4-methoxyisoquinolin-1-yl)oxy)pyrrolidine-1-carboxylate (1.3 g, 2.1 mmole) in DCM was added trifluoroacetic acid (TFA, 5 mL) at room temperature. The reaction mass was stirred at room temperature for 30 min. The solvent was evaporated under reduced pressure to get crude compound (2S,4R)—N-((1R,2S)-1-((cyclopropylsulfonyl)carbamoyl)-2-vinylcyclopropyl)-4-((4-methoxyisoquinolin-1-yl)oxy)pyrrolidine-2-carboxamide (1.05 g, 97.2%) as a TFA salt. The crude compound was taken to the next step without further purification. MS: MS m/z 501.3 (M++1).
