実験手順

Ammonium persulphate (102.7 g) in water (200 ml) was added over 40 minutes to a refluxing solution of 4-dimethylaminomethylpyridine (40.86 g), methanol (450 ml), water (210 ml) and concentrated sulphuric acid (30 ml). The resulting solution was refluxed for 2 hours, water (300 ml) was added and the methanol was distilled off. The cooled solution was basified and extracted with chloroform to give 4-dimethylaminomethyl-2-hydroxymethylpyridine (19.65 g) b.p. 92°-120°/0.06 mm Hg.
