실험 절차

A mixture of 3-fluoro-5,6-dimethyl-pyridine (0.230 g, 1.84 mmol) (Ife, R. J. Eur. Pat. Appl. (1987), EP 246774), 3-chloroperoxybenzoic acid (77%, 1.24 g, 5.5 mmol) in CH2Cl2 (25 mL) was stirred for 16 h. The solution was concentrated, and the residue was purified by flash chromatography on a silica gel column (8:1 EtOAc/MeOH), affording 3-fluoro-5,6-dimethyl-pyridine-1-oxide as a white solid (0.225 g 87%).
