Participants

Reaction Steps

55 g of solid 4-{1-[(2,6-dichloro-4-trifluoromethylphenyl)hydrazono]chloromethyl}benzonitrile are added in portions in the course of approximately one hour to 11.4 g of sodium cyanide in 270 ml of water and 400 ml of ethanol. After the mixture has been stirred for three hours at room temperature, 200 ml of ethanol and 135 ml of water are added and the mixture is stirred for a further 5 hours. 100 ml of water are added slowly, the precipitate is filtered off and washed with water, and the filter residue is dried in vacuo at 40°. This gives the title compound of melting point 186-187° (compound no. 3.4).
