A series of novel 5,6-disubstituted ethyl 3-amino-4-cyanothieno[2,3-b]pyridine-2-carboxylates was synthesized. The reaction conditions were thoroughly studied and intermediate ethyl 2-((3,4-dicyanopyridin-2-yl)thio)acetates were successfully isolated in good yields. For all synthesized compounds, spectral-fluorescent properties were carefully investigated and correlation thereof with chemical structure
