Procedure

To a solution of (S)-tert-butyl 4-(4-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)-5-(6-fluoroisoquinolin-3-ylcarbamoyloxy)pentanoyl)piperazine-1-carboxylate (56 mg, 0.081 mmol, 1.0 equiv.) in MeOH (1 mL) was added HCl (4 M in 1,4-dioxane, 1 mL). The mixture was stirred overnight and concentrated. The resulting residue was purified on RP-HPLC using a mixture of acetonitrile and H2O. The fractions containing the product were combined and concentrated. The resulting solid was dissolved in EtOAc. The organic solution was washed with saturated NaHCO3. HCl (4 N) was added into the organic solution. The solution was then concentrated to give (S)-2-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)-5-oxo-5-(piperazin-1-yl)pentyl 6-fluoroisoquinolin-3-ylcarbamate (35 mg, 65%) as a HCl salt. LRMS (M+H+) m/z 589.2.
