Versuchsvorschrift

9.63 g (56.6 mmol) [Bis(methylmercapto)methylene]-malononitrile was suspended in 50 ml water and treated with 3.7 ml (67.9 mmol) methylhydrazine. The mixture was heated at boiling for 1 hour, the reaction solution cooled, the precipitate suction filtered and recrystallised from ethanol.
