Versuchsvorschrift
Activated manganese dioxide (2.0 g) was added to a solution of 2-methoxy-3-hydroxymethyl-5-ethyl-6-methylpyridine (1.18 g, 6.5 mmol) in dry benzene (20 mL) and refluxed 5-10 hours. The warm suspension was filtered through a pad of anhydrous Na2SO4 and evaporated to yield 1.05 g (90%) of a viscous oil which solidified.
