実験手順

A mixture of 21.1 g. of 2-chloro-5-(4-chlorophenyl)pyridine and 19.5 g. of 95% hydrazine in 200 ml. of pyridine is heated at reflux temperature for 48 hours. The reaction mixture is cooled, poured into an ice-water mixture and filtered. The solid is collected, washed with water and air dried to yield 17.0 g. of the product of the Example as a tan solid.
