2,6-Diaminobenzonitriles, useful in the production of N-(2-cyano-3-substituted or unsubstituted amino-phenyl)oxamate and N-(2-cyano-3-substituted or unsubstituted amino-phenyl)tetrazole-5-carboxamide antiallergy and antisecretory agents, are prepared by sequential displacement of the fluoro substituents from 2,6-difluorobenzonitrile with the appropriately substituted amine.
2,6-二氨基苯腈是生产N-(2-氰基-3-取代或未取代氨基苯基)草酰氧甲酸和N-(2-氰基-3-取代或未取代氨基苯基)四唑-5-羧酰胺抗过敏和抗分泌剂的有用中间体,它们通过使用适当取代的胺依次取代2,6-二氟苯腈上的氟取代基而制备。
