Procedure

In 10 ml of methanol was dissolved 400 mg of (R)-3-(4-(2-(2-methyltetrazol-5-yl)pyridin-5-yl)-3-fluorophenyl)-5-methansulfonyloxymethyl oxazolidin-2-on prepared in the secondary step of the Example 24. The solution was added with 90 mg of sodium methoxide at room temperature and then stirred for one day at room temperature. The solution was extracted with ethyl acetate and the organic layer, thus separated, was washed with water and brine. The organic layer was dehydrated, filtered, concentrated in vacuo and purified by column chromatography to provide the title compound 200 mg. Yield 58%.
