実験手順
2-Methyl-4,5-di(hydroxymethyl)pyridine (0.1 mole) is stirred in pyridine (50 ml.) with acetic anhydride (0.1 mole) at room temperature overnight. The pyridine is evaporated and the residue is dissolved in 10 ml. water and extracted with 2 × 30 ml. of chloroform. After drying over magnesium sulfate, the chloroform is evaporated and the residue is chromatographed on a silica gel column using benzene-ethanol as eluate. By this procedure is obtained:
