Participants

Reaction Steps

Ammonia (20 microliters of an 8% ammonia solution in water) was added to a mixture of 2-(2,6-dichloro-4-trifluoromethylphenylhydrazono)succinonitrile (0.077 g) in ethanol (1 ml) and water (0.2 ml) at 0° C. After 10 minutes, the mixture was extracted (dichloromethane) and evaporated to give the title compound (0.076 g, 97% yield). Purity 98% (by hplc).
