Versuchsvorschrift

(5R)-3-[4-(1-{[(4S)-2,2-Dimethyl-1,3-dioxolan-4-yl]carbonyl}-1,2,3,6-tetrahydropyridin-4-yl)-3,5-difluorophenyl]-5-[(4-methyl-1,2,3-triazol-1-yl)methyl]oxazolidin-2-one (Intermediate 55) (542 mg, 1.08 mmol) was dissolved in tetrahydrofuran (20 ml). A solution of hydrochloric acid (1N, 10 ml) was added and the reaction mixture was stirred at room temperature. After 64 hours, the solution was poured into ethyl acetate the aqueous was extracted with ethyl acetate. The aqueous was basified with a solution of 10% aqueous sodium acetate and re-extracted with ethyl acetate. The combined organics were dried over magnesium sulfate and concentrated under vacuum. Chromatography on silica gel with 10% methanol in ethyl acetate gave 254 mg of the title product.
