By reaction and treatment in the same manner as in Preparation Example 25 and using 1-amino-3-methoxypropan-2-ol (1 g), 5-methoxymethyloxazolidin-2-one (620 mg) was obtained. To a mixture of 5-methoxymethyloxazolidin-2-one (620 mg), ethyl 4-iodobenzoate (1.6 mL), potassium carbonate (2.6 g) and copper (I) iodide (552 mg) were added toluene (20 mL) and N,N′-dimethylethylenediamine (625 μL), and the mixture was refluxed for 8 hr. After cooling, water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, and the solvent was evaporated to give the title compound (830 mg).
