Reaction Steps

To a solution of (2S,4R)-2-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)-4-hydroxy-5-(phosphonooxy)pentyl isoquinolin-3-ylcarbamate in MeOH (50 mL) at 0° C. was added NaOH solution (0.5 N, 16 mL, 2 equiv.) dropwise. The solution was stirred at 0° C. for 1 h and concentrated to give sodium (2R,4S)-4-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)-2-hydroxy-5-(isoquinolin-3-ylcarbamoyloxy)pentyl phosphate as a white solid (quant.). The solid could be further crystallized by trituration with EtOH, followed by re-crystallization from EtOH—H2O (6:1) to give the crystalline form. LRMS (M−2Na+3H+) m/z 585.5.
