A convenient method for the synthesis of novel sulfonic cytosine derivatives, 8-(methyl(phenyl)sulfonyl)-2,6-dihydroimidazo[1,2-c]-pyrimidin-5(3Н)-ones and 9-(methyl(phenyl)sulfonyl)-2,3,4,7-tetrahydro-6H-pyrimido[1,6-a]pyrimidin-6-ones, has been developed based on the reaction of 3-amino-2-(methyl(phenyl)sulfonyl)acrylonitriles with 2-chloroethyl isocyanate and 3-chloropropyl isocyanate. The resulting heteryl sulfones possess antiviral activity.
