HCID 765456-Chloromethyl-2-methylpyridinium chloride

Procedure

2-(Hydroxymethyl)-6-methylpyridine (3.7 g, 29.4 mmol) was added portion wise at 0° C. to thionylchloride (35 mL, 477 mmol). The reaction mixture was then stirred at room temperature for 18 h. Excess thionylchloride was removed under vacuum and the crude 2-chloromethyl-6-methyl-pyridine hydrochloride (5.1 g, light brown solid) was used without any further purification.
