3-{4-[(5R)-5-(Azidomethyl)-2-oxo-1,3-oxazolidin-3-yl]phenyl}-1-methyl-1H-pyrazole-5-carbonitrile (Intermediate 14, 00 mg, 0.62 mmol), bicyclo[2.2.1]hepta-2,5-diene (0.70 ml, 6.50 mmol) and dioxane (5 ml) were combined and warmed to 90° C. for 8 hours. The mixture was evaporated and purified by chromatography on silica gel eluting with ethyl acetate to give the title compound as an off-white solid (110 mg).
