Sulfuryl chloride → HCID 21393472, compound

Participants

Reaction Steps

To a solution of 92.2 g. (0.434 mole) 2-methoxy-3,5,6-trichloropyridine in 400 ml. carbon tetrachloride, which is illuminated and heated to reflux by a G.E. sunlamp, add dropwise over a period of 5 hours a solution of 58.6 g. (0.434 mole) sulfuryl chloride in 400 ml. carbon tetrachloride. The mixture is allowed to reflux for 1 hour, then is cooled and the solvent is evaporated in vacuum. The residue is a colorless liquid which is distilled through a 4-inch fractionating Claisen head to afford a pure fraction of 2-chloromethoxy-3,5,6-trichloropyridine, 52.5 g. (49%), b.p. 106°-110° C. at 1.3 mm. Hg.
