Versuchsvorschrift

A solution of 25.5 gm (0.1 mol) of potassium 2,5-dichloro-4-methylmercapto-phenolate and 16.2 gm (0.1 mol) of 2,4-dichloro-6-methyl-pyridine in 100 ml of dimethylformamide was heated under reflux for 5 hours. It was then cooled and poured into 300 ml of water. The precipitate which separated out was recovered by suction filtration, washed with water, and recrystallized from isopropanol.
