Procedure

4-hydroxymethyl-2-(3,4,5-trimethoxyphenyl)pyridine(19.18 g) was dissolved in chloroform (100 mL), and to the solution thinly chloride (10.2 mL) was added at 0° C. After 30 minutes, the mixture was warmed to room temperature and stirred for 4 hours. The reaction mixture was washed with aqaueous saturated sodium hydrogendcarbonate and brine, dried over anhydrous sodium sulfate and evaporated. The residue was then recrystallized from ethyl acetate-hexane to give the title compound as pale yellow crystalline powder.
