反応手順
Prepared by the general method of Example 1 using as starting material 5(R)-hydroxymethyl-3-(4-(1-benzyl-1,2,5,6-tetrahydropyrid-4-yl)-3-fluorophenyl)oxazolidin-2-one (WO97/30995; 4.0 g, 10.5 mmol), 3-hydroxyisoxazole (1.0 g, 11.8 mmol), triphenylphosphine (3.24 g, 12.4 mmol) and diisopropylazodicarboxylate (2.36 g, 11.7 mmol) in tetrahydrofuran (60 ml). Purified by flash chromatography (Merck 9385 silica; tert-butyl methyl ether/EtOAc/MeOH (70:30:0.5) eluant) to give the product (3.0 g, 64%) as a colourless crystalline solid. MS: ESP30 (M+H)+=450.
