実験手順
40 g of 2-acetoxymethyl-4,6-dichloro-5-n-butyl-pyridine in 200 ml of 6 N hydrochloric acid are boiled for 15 hours under reflux. Thereafter the mixture is evaporated to dryness. The residue is taken up in chloroform and extracted by shaking with aqueous potassium carbonate solution. The chloroform solution is dried and evaporated. Fractional distillation yields 2-hydroxymethyl-4,6-dichloro-5-n-butyl-pyridine of boiling point 150°-160° (0.1 mm Hg).
