Thionyl Chloride → 3-(6-Chlorohexyl)pyridine

Participants

Reaction Steps

A solution of 22 g of 6-(3-pyridyl)hexanol in 100 ml of chloroform was cooled in an ice bath and treated with a solution of 21.9 g of thionyl chloride in 50 ml of chloroform. The reaction mixture was allowed to warm to room temperature over 1 hour, was heated to a bath temperature of 60° C. for 1 hour and was concentrated. The residue was taken up in chloroform, washed with saturated potassium carbonate, dried, and evaporated. The residue was distilled to give 20.5 g (84%) of 6-(3-pyridyl)hexylchloride, bp 180°-190° C./0.15 mm.
