1.00 g (8.12 mmol) 3-(hydroxymethyl)-2-methylpyridine are initially introduced into the reaction vessel and 5.9 ml (81.2 mmol) thionyl chloride are slowly added at 0° C. The mixture is stirred under reflux for 3 h. It is concentrated, saturated sodium bicarbonate solution is added to the residue and the mixture is extracted several times with diethyl ether. The combined organic phases are washed with saturated sodium chloride solution, dried over sodium sulfate, filtered and concentrated.
