Procedure

To a solution of (6-Fluoro-isoquinolin-3-yl)-carbamic acid (S)-5-(2-tert-butoxycarbonylamino-acetylamino)-2-[3-(2-chloro-3-fluoro-benzyl)-1-methyl-ureido]-pentyl ester (105 mg, 0.16 mmol) in DCM (10.0 mL) was added TFA (1.0 mL). The mixture was stirred at RT for 2 h. The mixture was concentrated and re-dissolved DCM. The DCM layer was washed with K2CO3 (2 N), saturated NaHCO3, and brine, dried over Na2SO4, filtered, and concentrated. The residue was purified on silica gel column using a mixture of DCM and MeOH to give (S)-5-(2-aminoacetamido)-2-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)pentyl 6-fluoroisoquinolin-3-ylcarbamate (71 mg, 79%). LRMS (M+H+) m/z 563.2.
