AMINOMALONONITRILE P-TOLUENESULFONATE Usage And Synthesis

Uses	Aminomalononitrile p-toluenesulfonate was used in the syntheiss of 1-substituted 5-amino-4-cyano-2-hydroxyimidazoles.
Uses	Aminomalononitrile p-toluenesulfonate is a reagent for diazonamide synthesis via heck endocyclization. It may also have implications for developing IκB Kinase-β inhibitors.
Purification Methods	It forms colourless crystals on recrystallisation from MeCN (1.8g in 100mL) using activated charcoal. Wash the crystals with dry Et2O and dry them at 25o/1mm. Recovery is ~80%. [Ferris et al. Org Synth Coll Vol V 32 1973.]
