Diazoamino Coupling of a 4-Sulfobenzenediazonium Salt with Some Cyclic Amines

摘要

Preparation of several novel potassium salts of 4-substituted aminoazo-benzenesulfonic acids by the simple and convenient reaction of insoluble 4-sulfo-benzenediazonium chloride with some (hetero)cyclic amines of various ring sizes is reported. The compounds obtained have shown potential antiinflammatory activity in biological testing.
