A one-pot synthesis of ethyl 8,9-difluoro-6-oxo-6H-benzo[c]quinolizine-5-carboxylate 11 has been developed. The condensation of ethyl 2-pyridylacetate and 2,4,5-trifluorobenzoyl chloride followed by intramolecular nucleophilic aromatic substitution gave the desired ring system. This intermediate was converted to the title compound and its in vitro biological activity is reported.
已经开发了一锅合成的8,9-二氟-6-氧代-6 H-苯并[ c ]喹啉嗪-5-羧酸乙酯11。将2-吡啶基乙酸乙酯和2,4,5-三氟苯甲酰氯缩合,然后进行分子内亲核芳族取代,得到所需的环系统。将该中间体转化为标题化合物,并报道了其体外生物学活性。
