Abstract: A novel and convenient method for the preparation of 4-(4-aminophenyl) urazole has been developed. Protic diazotization of amino group of this compound and subsequent coupling reaction with some electron rich aromatic compounds such as phenols, naphthols, and ani lines lead to the formation of novel azo dyes with a phenylurazole linkage in moderate to high yields.
