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.
