Reaction Steps

A mixture of 22 g of 3-(2-chlorophenoxy)pyridine 1-oxide and 22 g of dimethylsulfate is heated at 100° C. for 4 hours. The 3-(2-chlorophenoxy)-1-methoxypyridinium methosulfate is cooled and dissolved in 100 ml of water. This solution is added dropwise with stirring to a 0°-5° C. solution of 50 g of sodium cyanide in 100 ml under a nitrogen atmosphere. The mixture is stirred 16 hours and extracted with 250 ml of chloroform. The extract is dried, concentrated and distilled to yield 3-(2-chlorophenoxy)-2-pyridine-carbonitrile, bp 125°-135° C. at 01. mM, mp 90°-92° C. after recrystallization from isopropanol.
