Trimethylsilyl iodide → HCID 57948021, compound

Participants

Reaction Steps

To a solution of (2S)-2-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)-5-(dimethoxyphosphoryloxy)-4-hydroxypentyl 6-fluoroisoquinolin-3-ylcarbamate (0.15 g, 0.238 mmol, 1.0 equiv.) in acetonitrile (2 mL) was added TMSI (0.162 mL, 1.19 mmol, 5.0 equiv.) at RT After stirred at RT for 10 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 H2O (0.1% TFA buffer) to give the desired product. The product was dissolved in a mixture of methanol and water (2:1), and HCl (4 M in 1,4-dioxane, 2 mL) was added. The solvent was removed. This procedure was repeated to give (2S)-2-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)-4-hydroxy-5-(phosphonooxy)pentyl 6-fluoroisoquinolin-3-ylcarbamate (98 mg, 64%) as a HCl salt. LRMS (M+H+) m/z 603.0.
