Reaction Steps

Tert-butyl (S)-1-(3-fluorophenyl)-2-hydroxyethylcarbamate (256 mg, 1.0 mmol) was dissolved in acetonitrile (10 mL) and treated with cesium carbonate (391 mg, 1.2 mmol) and ethyl bromoacetate (0.14 mL, 1.25 mmol). The mixture was heated to 100° C. for 30 min, then cooled to room temperature, acidified, and extracted with ethyl acetate. Purification on silica gel (15%-40% ethyl acetate/hexanes) gave 69 mg of tert-butyl (S)-2-((ethoxycarbonyl)methoxy)-1-(3-fluorophenyl)ethylcarbamate as a colorless glass. HPLC-MS calculated for C17H24FNO5 (M+H+) 342.2, found 342.1.
