Reaction Steps
Methyl hydrazine (4.2 g) was added slowly to benzaldehyde (9.4 ml) in 2-methoxyethanol (15 ml) causing the solution to boil. The solution was heated under reflux for 20 minutes and was then added to a solution of bis(methylmercapto)methylenemalononitrile (15.6 g) in 2-methoxyethanol (75 ml). The solution was heated under reflux for 6 hours and was then cooled to 0° C. to precipitate benzaldehyde N-methyl-N-(2,2-dicyano-1-methylmercaptoethenyl) hydrazone (5.6 g), m.p. 159°-160° C.
