Procedure

To a solution of the above crude (2S,4R)-2-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)-5-(di-tert-butoxyphosphoryloxy)-4-hydroxypentyl isoquinolin-3-ylcarbamate in MeOH (8 mL) at 0° C. was added conc. HCl (12 N, 8 mL, 20 equiv.) dropwise. The mixture was stirred for 30 min and concentrated. The residue was dissolved in 50 mL H2O. Aqueous NaOH solution (1 N) was added to adjusted the PH to 3˜4. EtOAc (50 mL) was then added. The mixture was stirred at RT for 1 h. The white solid was then filtered and washed with H2O and EtOAc, followed by drying in vacuo to give (2S,4R)-2-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)-4-hydroxy-5-(phosphonooxy)pentyl isoquinolin-3-ylcarbamate as a white powder (2.4 g, 86% for 2 steps). LRMS (M+H) m/z 585.5.
