Goswami, Shyamaprosad published the artcileSide chain bromination of mono and dimethyl heteroaromatic and aromatic compounds by solid phase N-bromosuccinimide reaction without radical initiator under microwave, Synthetic Route of 14903-78-7, the publication is Chemistry Letters (2004), 33(7), 916-917, database is CAplus.
A series of side chain mono and dibromo derivatives of mono and di-Me heteroaromatic and aromatic compounds were synthesized by one step solid phase N-bromosuccinimide (NBS) reaction without radical initiator by microwave irradiation The benzylic mono and dibromo products were exclusively preferred except in the case of 6-methylpyridine amides where nuclear and side chain bromination resulted. Naphthyridine systems gave improved yields. Synthesis of 2-pivaloylaminopterin-6-carbaldehyde is reported.
