Abstract

2-Phenyl-1, 8-naphthyridin-4-ones had been synthesized for their cytotoxic activity. Substituted acetophenone was treated with NaH and diethyl carbonate to give ethyl benzoylacetates, which was reacted with substituted 2-aminopyridine and PPA to yield 2-phenylpyridopyrimidine-4-ones. These compounds was heated at $350^\times$C in liquid paraffin to afford final compounds, 2-phenyl-1 , 8-naphthyridin-4-ones.
