The first representative of the &substituted 4-thiolumazine series has been synthesized. In a sequence of reactions, 4,6-dichloropyrimidin-2-( 1 H)-one (1) is first converted into 4-chloro-6-(methylamino)pyrimidin-2( 1H)one (6), then the Cl-atom displaced by the thioxo group ( +7) followed by a coup
