Reaction Steps

Ethyl 2-diazo-3-(2-fluorophenyl)-3-oxopropanoate (1.06 g, 4.49 mmol) was dissolved in acetonitrile (20 mL), cooled to 0° C. and treated with tri-n-butylphosphine (1.16 mL, 4.71 mmol, 1.05 equiv). The mixture was warmed to ambient temperature and after 10 minutes, was concentrated in vacuo. The residue was purified via silica gel gradient chromatography (100:0 to 75:25; hexanes:ethyl acetate) to provide the titled compound.
