2-Alkyl- and 2-aryl-4-oxo-4H-thiopyrano[2,3-b]pyridine can be conveniently prepared by reacting the appropriate aromatic and aliphatic O-ethyl thiocarboxylates with the sodium derivative of various alkyl 3-(2-bromopyridyl) ketones.
2-烷基和2-芳基-4-氧代-4H-噻吡啶[2,3-b]吡啶可通过与适当的芳香和脂肪族O-乙基硫代羧酸酯反应,制备得到各种烷基3-(2-溴吡啶基)酮的钠衍生物,从而方便地合成。
