Reaction Steps

(5R)-3-[3-Fluoro-4-(4-methyl-1,2,3-triazol-1-yl)phenyl]-5-[(methanesulfonyl)methyl]-oxazolidin 2-one (Intermediate 18) (5.0 g, 13.5 mmol) was dissolved in DMF (45 ml). Sodium azide (1.75 g, 27.0 mmol) was added and the reaction mixture was stirred at 70° C. for one hour. It was partitioned between ethyl acetate and saturated sodium bicarbonate, the organic phase was washed with water and brine, dried over magnesium sulfate and concentrated under reduced pressure to give the product as a white solid (4.1 g), which was used without further purification.
