Detalhes bibliográficos
Resumo:ln recent years we have been interested in the synthesis of diarylamines in the benzo[b]thiophene series functionalizing either the benzene or the thiophene2 ring. Here we describe the synthesis of new 7-aryl or heteroarylamino-2,3-dimethylbenzo[b]thiophenes, reacting, the also prepared 7-bromo or 7-amino-2,3-climethylbenzo[b]thiophenes with anilines and 3-aminopyridine or bromobenzenes anel 2-bromopyridine, respectively, under palladium-catalyzed C-N cross-coupling conditions (Scheme).
