Unusual reaction of 4-nitrobenzofurazan with amines

The treatment of 4-nitrobenzofurazan with secondary amines resulted in the formation of 4-amino-5,7-bis(dialkylamino)-benzofurazans, as established by X-ray diffraction analyses; this is the first example of S N H reaction with synchronous alteration of three functions.
