Procedure

The carbamate prepared as above (0.37 g, 1.82 mmol), (5R)-3-(3-fluoro-4-{6-[(5S)-5-(hydroxymethyl)-4,5-dihydroisoxazol-3-yl]pyridin-3-yl}phenyl)-5-(1H-1,2,3-triazol-1-ylmethyl)-1,3-oxazolidin-2-one (Example 1: 0.2 g, 0.46 mmol), 4-dimethylaminopyridine (0.01 g, 0.08 mmol), and 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride (0.19 g, 0.99 mmol) were combined in DMF (2 ml). The suspension was allowed to stir for 3.5 hours at room temperature resulting in a clear solution. The mixture was then diluted with ethyl acetate, washed with water, and dried over magnesium sulfate. The residue obtained upon filtration and evaporation was purified via chromatography (silica gel, 0.5 to 10% methanol in dichloromethane). Evaporation of the product containing fractions and trituration of the resulting solid with diethyl ether yielded the title compound as an off-white powder (0.225 g), melting point: 103° C.
