Procedure

To a solution of 2-(ethoxymethylene)malononitrile (15.2 g, 0.124 mole) in 100 ml toluene was added Intermediate 1-benzylidene-2-ethylhydrazine (18.4 g, 0.124 mole). The mixture was allowed to stand at room temperature, and a precipitate formed. The reaction mixture was stirred for an additional 16 h. The precipitate was collected on a filter and washed with a small amount of cold ethanol to obtain 2-((2-benzylidene-1-ethylhydrazinyl)methylene)malononitrile as a solid.
