Highly efficient, mild synthetic protocols were developed for the oxidative bromination of deactivated aminoanthracene-9,10-diones by using H2O2-HBr and m-CPBA-HBr in methanolic medium. Both the protocols offer excellent bromine atom economy, good conversion (100%) along with high yield (82-93%) and high purity of desired product. The N-alkylated amines undergo regio-selective bromination to give selective p-bromo product. The commercial availability of all the starting materials, simple reaction procedure and ease of work up, and easily amenable for scale up demonstrated commercial feasibility of both the protocols.
