Procedure

To a mixture of (S)-5-azido-2-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)-4,4-difluoropentyl 6-fluoroisoquinolin-3-ylcarbamate (25.0 g, 0.0441 mol), THF (300 mL) and water (100 mL) was added triphenylphosphine (13.9 g, 0.0529 mol) and aq. HCl solution (53 mL, 2N, 0.106 mol). The resulting mixture was stirred at RT for 1 h and concentrated down to about 200 mL. Water (200 mL) was then added. The resulting mixture (pH<4) was extracted with EtOAc (300 mL) and the EtOAc solution was discarded. The remaining aq. solution was adjusted to pH>8 by adding NaOH (2N) and extracted with DCM (200 mL×3). The organic layer was washed with water and brine, dried over Na2SO4. The organic layers were combined and concentrated. The resulting residue was purified on silica gel column (DCM/MeOH) to give (S)-5-amino-2-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)-4,4-difluoropentyl 6-fluoroisoquinolin-3-ylcarbamate (12.1 g, 50.7%). LRMS (M+H+) m/z 542.5.
