3-Nitrophenol (0.92 g, 6.6 mmol) was dissolved in 5 ml anhydrous DMF, and cesium fluoride (3.02 g, 19.9 mmol) was added. The reaction mixture was stirred for 1 hour at room temperature, and (S)-glycidyl nosylate (1.71 g, 6.6 mmol) was added. The reaction mixture was stirred for 20 hours at room temperature. Water (150 ml) was added, and the solution was extracted with ethylacetate. The organic phase was dried over MgSO4 and evaporated. The residue was purified with column chromatograph using ethylacetate:hexane (50:50) solvent to give (S)-glycidyl m-nitrophenyl ether (1.02 g 80% yield, m.p 44-5° C.) as a yellowish solid.
