Reaction Steps

390 mg of 3-[3-(4-Benzyl-2-(oxo)-oxazolidin-3-yl)-2-isopropoxy-3-oxo-propyl]-phenyl trifluoromethanesulfonate was dissolved in 2 ml of N,N-dimethylformamide, 85 mg of propargyl alcohol, 8 mg of copper iodide, 45 mg of tetrakis (triphenylphosphine) palladium and 0.3 ml of triethylamine were added in succession, and the mixture was stirred overnight at 50° C. under a nitrogen atmosphere. The reaction solution was filtered through silica gel, and the filtrate was dissolved in ethyl acetate, washed with water, 1N hydrochloric acid and saturated brine. The organic layer was dried over anhydrous magnesium sulfate, and the solvent was evaporated. The residue was purified by silica gel column chromatography, to give 207 mg of the title compound as a colorless oil in the 3:2 hexane-ethyl acetate fraction.
