Reaction Steps

(5R)-3-(3-Fluoro-4-{6-[(5S)-5-(hydroxymethyl)-4,5-dihydro-3-isoxazolyl]-3-pyridinyl}phenyl)-5-(1H-1,2,3-triazol-1-ylmethyl)-1,3-oxazolidin-2-one (Example 1, 200 mg, 0.46 mmol) was suspended in 2 mL of anhydrous dimethylformamide. Anhydrous pyridine (2 mL, 24 mmol), 4-dimethylaminopyridine (DMAP) (20 mg, 0.17 mmol) and di-O-acetyl-L-tartaric anhydride (210 mg, 0.97 mmol) were added and the solution was stirred for 16 hours at room temperature during which the mixture turned black. The reaction was quenched with 1 mL of methanol, the solvents evaporated in vacuo and the product isolated by flash chromatography on silica using a gradient from 0 to 5% methanol in dichloromethane to yield 50 mg (25%) of the title compound as an off white solid.
