Versuchsvorschrift

20 ml of 2-n-propylpyridine were dissolved in 60 ml of glacial acetic acid, mixed with 40 ml of H2O2 (30%) and stirred for 16 hours at room temperature and 3 hours at 65° C. The acetic acid was then partly rotated out, the residue was adjusted to pH 8 with NaOH (20%), extracted with dichloromethane and the organic phase rotated in to dryness. 20 g of crude 2-propylpyridine-N-oxide were obtained.
