Procedure

To a solution of (S)-2-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)-5-(dimethoxyphosphoryloxy)-4,4-dimethylpentyl 6-fluoroisoquinolin-3-ylcarbamate (0.5 g, 0.79 mmol) in acetonitrile (50 mL) was added TMSI (0.848 mL, 6.23 mmol) at 0° C. After stirred at 0° C. for 30 min, the reaction was quenched with MeOH. The solvent was removed and the resulting residue was purified on RP-HPLC using a mixture of acetonitrile and water (0.1% HCOOH buffer) to give (S)-2-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)-4,4-dimethyl-5-(phosphonooxy)pentyl 6-fluoroisoquinolin-3-ylcarbamate (340 mg, 71.1%). LRMS (M+H+) m/z 615.5.
