摘要: Abstract Efficient one-pot three component reaction of aniline derivatives with cyanoamide and triethyl orthoformate at reflux in toluene affords N′-aryl-N-cyanoformamidines high yields just by the distillation azeotrope toluene/ethyl alcohol. Labelled d9-Amitraz is prepared application this procedure synthesis formamidine pesticides family.
