A mixture of 3-(2-hydroxyethyl)pyridine (1.2 g., 9.8 m.moles ) and thionyl chloride (10 ml.) was refluxed for 3 hours and then excess of the thionyl chloride was removed by evaporation. To the residue was added a 5% aqueous solution of Na2CO3 (20 ml.) and the mixture was extracted with chloroform (2×30 ml.). The extracts were combined, dried with anhydrous Na2SO4 and concentrated to dryness to yield 3-(2-chloroethyl)-pyridine, 1.3 g. (98%).
