Versuchsvorschrift

To a 0° C. solution of 2,6-dimethylpyridine (1.0 g, 0.009 mol) in CHCl3 (25 mL) was added mCPBA (3.17 g, 0.01 mol). The reaction mixture was then stirred for 12 h at RT, quenched with a saturated Na2CO3 solution. The organic layer was separated, dried over Na2SO4 and concentrated in vacuo to afford 2,6-dimethylpyridine 1-oxide (980 mg, 85%) as a solid.
