Compounds of the formula ##STR1## where R is hydrogen, methyl, ethyl, propyl, 2-propenyl or 2-propynyl; and R' is hydrogen or fluoro possess anti-inflammatory activity. The compounds where R is H are prepared by reacting a compound of the formula ##STR2## with (1H,3H)-pyrimidine-2,4,5,6-tetrone. The compounds where R is other than hydrogen are prepared by reacting a compound where R is hydrogen with the appropriate alkylating agent.
式为##STR1##的化合物,其中R为氢、甲基、乙基、丙基、2-丙烯基或2-丙炔基;R'为氢或氟的具有抗炎活性。其中R为H的化合物通过将式为##STR2##的化合物与(1H,3H)-嘧啶-2,4,5,6-四酮反应制备。而R不是氢的化合物则通过将R为氢的化合物与适当的烷基化剂反应制备。
