2-Chloronicotioyl isothiocyanate reacted with substituted 2-aminopyrimidine under the alkali condition to give 2-(pyrimidin-2-yl)amino-4H-pyrido[3,2-e][1,3]thiazin-4-one directly. Six 2-(pyrimidin-2- yl)amino-4H-pyrido[3,2-e][1,3]thiazin-4-one compounds were synthesized. The structures of these compounds were confirmed by IR, 1H NMR spectra and elemental analyses. A possible mechanism of the reaction was proposed.

Key words: substituted 2-aminopyrimidine, 2-(pyrimidin-2-yl)amino-4H-pyrido-[3,2-e]- [1,3]thiazin-4-one, synthesis, isothiocyanate
