In 1st Symposium on Medicinal Chemistry. Braga Several thienopyridines have already been described as inhibitors of cell proliferation using human tumor cells[1,2], highlighting the interest of studying their antitumorpotential. ln this work, we present the synthesis of di(hetero)arylthioethers 1a-fby SNAr of the 7-chloro thieno[3,2- b]pyridine with amino or methoxy thiophenols in good to high yields, like presented in the scheme.engconference object
