✦ Synopsis

Radical bromination of 4,5-dimethylthiazole (1) was carried out using different stoichiometries of N-bromosuccinimide in the presence of 2,2Ј-azobisisobutyronitrile. Mono-, tri-and tetrabromo compounds 2, 5, and 6 were obtained in good yields with regioselectivity while the dibromo derivatives 3 and 4 were formed without any selectivity. Substitution at the
