Reaction Steps

2-(2,6-Dichloro-4-trifluoromethylphenyl]-4-[2,2-di(methylthio)ethyl]-2H-1,2,3-triazole was treated with N-bromosuccinimide in aqueous acetonitrile., After 10 minutes the mixture was added to water and extracted with diethyl ether. The extract was worked up to give crude 2-(2,6-dichloro-4-trifluoromethylphenyl)-2H-1,2,3-triazole-4-acetaldehyde. This was then treated with diaminomaleonitrile in a similar manner to Example 1, to give 2-(2,6-dichloro-4-trifluoromethyl-phenyl]-4-[2-(2-amino-1,2-dicyanoethenylimino)ethyl]-2H-1,2,3-triazole, which was cyclised in a similar manner to Example 1a, to give 2-(2,6-dichloro-4-trifluoromethyl-phenyl)-4-[(4,5-dicyano-1H-imidazol-2-yl)methyl]-2H-1,2,3-triazole (Compound 30).
