Procedure

To a solution of (S)-3-(2-tert-butoxycarbonylaminoacetamido)-2-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)propyl 6-fluoroisoquinolin-3-ylcarbamate (0.87 g, 1.37 mmol) in DCM (30.0 mL) was added TFA (3.0 mL). The mixture was stirred for 1 h. The mixture was concentrated and dissolved in EtOAc. The EtOAc solution was washed with Na2CO3, brine, dried over Na2SO4, and filtered. To the filtrate was added HCl (4 M in dioxane, 0.7 mL, 2.8 mmol,). The organic solvent was removed under reduced pressure to give (S)-3-(2-aminoacetamido)-2-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)propyl 6-fluoroisoquinolin-3-ylcarbamate (730 mg, 93%) as a HCl salt. LRMS (M+H+) m/z 535.2.
