Oxazole Ring Cleavage in the Course of the Synthesis of Heterocyclic Azo Dyes

The formation of azo dyes by coupling the diazonium salts of aminophenyloxazolopyridines with N,N-diethylaniline was shown to be a suitable probe to check the stability of the oxazole ring in the course of their preparation.Depending on experimental condi
