Procedure

To a solution of (S)-methyl 5-(3-(2,3-difluorobenzyl)-1-methylureido)-6-(isoquinolin-3-ylcarbamoyloxy)hexanoate (1.45 g, 2.04 mmol, 1.0 equiv.) in 1,4-dioxane (18 mL) was added aqueous LiOH (6.12 mL, 6.12 mmol, 3.0 equiv.) at RT After stirred at RT for 1 h, the reaction mixture was acidified with HCl (1.0 N) to pH ˜3. The mixture was extracted with EtOAc twice. The combined EtOAc solution was washed with brine, dried over Na2SO4, and concentrated under vacuum to give (S)-5-(3-(2,3-difluorobenzyl)-1-methylureido)-6-(isoquinolin-3-ylcarbamoyloxy)hexanoic acid, which was used without further purification. LRMS (M+H+) m/z 501.3.
