Reaction Steps

5(R)-hydroxymethyl-3-(3-fluoro-4-(3,6-dihydro-(2H)-pyran-4-yl)phenyl)oxazolidin-2-one (300 mg, 1.02 mmol), 3-hydroxy-5-methylisoxazole (120 mg, 1.21 mmol), triphenylphosphine (270 mg, 1.03 mmol) and diisopropylazodicarboxylate (204 mg, 1.01 mmol) were reacted in THF (8.0 ml) using the general method of Example 1. The resultant product was purified by flash chromatography (Merck 9385 silica, EtOAc/isohexane (7:3) eluant) to give the title product (176 mg, 46%) as a crystalline solid.
