Potassium Carbonate → HCID 66877432, compound

Participants

Reaction Steps

Methyl bromoacetate (47 L, 0.495 mmol), followed by potassium carbonate (136.7 mg, 0.99 mmol) were added to a solution of 3-[4-(3-fluoro-benzenesulfonyl)-2-hydroxy-phenyl]-pyrrolidine-1-carboxylic acid tert-butyl ester (198.7 mg, 0.471 mmol) in acetone (5 mL) under argon atmosphere. The reaction mixture was stirred at room temperature for 4 hours, then filtered and the solvent was evaporated under reduced pressure to give 240.9 mg of 3-[4-(3-fluoro-benzenesulfonyl)-2-methoxycarbonylmethoxy-phenyl]-pyrrolidine-1-carboxylic acid tert-butyl ester, which was used without further purification in the next step.
