Abstract

The selective protection of the triazole function of 5-aminobenzotriazole is reported. Two different protecting groups were used to prevent side reactions through the triazole amine acting as a leaving group when 5-aminobenzotriazole was used as a nucleophile. This allowed the addition of aminobenzotriazole to two target molecules to impart metal complexing properties to the new species.
