Flourinated 4-imino-3,5,7-trisubstituted-pyrido [2,3-d] pyrimidine-2(1H) thiones have been synthesised in good yields by the reaction of 2-amino-3-cyano-4,6- disubstituted-pyridines with various arylisothiocyanates. These new type of products have been characterised by elemental analysis, IR, 1H and 19F NMR spectral studies.
