A solution of 2.60 g (0.022 mol) of thionyl chloride in 10 ml of chloroform was dropwise added to a solution of 3.64 g (0.018 mol) of 2-hydroxymethyl-4-methoxypropoxypyridine in 60 ml of chloroform under cooling with ice. The obtained mixture was stirred for one hour, neutralized with a saturated aqueous solution of sodium hydrogencarbonate and extracted with chloroform. The chloroform layer was dried over magnesium sulfate and filtered. The filtrate was concentrated under a reduced pressure to obtain 3.23 g of the title compound as a crude product.
