Abstract: 5,7-Dimethoxy-8-(3,6-diphenylpyridin-2-yl)coumarins were obtained from 5,7-dimethoxycoumarins and 3,6-diphenyl-1,2,4-triazines via the protocol comprising aromatic $\mathrm{S_N^H}$ substitution in the triazine ring followed by the Boger transformation of formed triazine moiety into the pyridine one. The advantages of the suggested method are simple procedures, high yields, and the absence of transition-metal catalysts.
