Dimethylformamide → 5-(Phenoxymethyl)-1,3-oxazolidin-2-one

422 mg of N,N'-carbonyldiimidazole were added, whilst ice-cooling, to a solution of 500 mg of 3-phenoxy-2-hydroxypropylamine in 5 ml of anhydrous dimethylformamide, and the mixture was stirred at room temperature overnight. At the end of this time, the solvent was removed from the reaction mixture by evaporation under reduced pressure, and water was added to the resulting concentrate. The mixture was then extracted with ethyl acetate. The extract was washed with an aqueous solution of sodium chloride and dried over anhydrous sodium sulfate. The ethyl acetate was removed from the extract by evaporation under reduced pressure, and the resulting residue was purified by silica gel column chromatography, using ethyl acetate as the eluent, to give 490 mg of the title compound, melting at 110° C. to 111° C.
