実験手順: A solution of 9.4 g of alpha,2-dichloro-6-methyltoluene in 30 ml of 95% ethanol is treated with a solution of 3.8 g of potassium cyanide in 5 ml of water and heated at reflux for 6 hours. The crude product is isolated by pouring the cooled reaction mixture into water and filtering the precipitated solid. Recrystallization from aqueous ethanol gives 4.9 g of pure 2-chloro-6-methylphenylacetonitrile, mp 49°-51° C., in two crops. heated at reflux for 6 hours The crude product is isolated by pouring filtering the precipitated solid Recrystallization from aqueous ethanol

実験手順: The 2-chloro-6-methylbenzyl alcohol is dissolved in 100 ml of benzene, treated with 25 ml of thionyl chloride and the mixture is heated at reflux for 3 hours. Concentration of this mixture to dryness leaves a liquid which partly solidifies. The product containing liquid is decanted from the solid by-product and distilled to yield 7.8 g of alpha,2-dichloro-6-methyltoluene as a colorless liquid with bp. 118°-122° C./17-18 mm of Hg. the mixture is heated at reflux for 3 hours Concentration of this mixture to dryness leaves a liquid which The product containing liquid is decanted from the solid by-product distilled
