Versuchsvorschrift

Benzenesulfonyl hydrazine (20.5 g, 0.12 mole) was dissolved by warming in 110 ml absolute ethanol. p-Cyanobenzaldehyde (15.6 g, 0.12 mole) was separately dissolved in 50 ml of hot ethanol and added to the hydrazine solution. The resulting slurry was refluxed 0.5 hour, cooled and filtered to yield 28.1 g; m.p. 209°-213°. Recrystallization from CH3CN gave purified title product: 23.7 g; m.p. 210°-213°.
