Nitrogen Attached Directly To The Six-membered Hetero Ring By Nonionic Bonding Patents (Class 546/297)
  • Patent number: 5563160
    Abstract: The present invention relates to hitherto unknown compounds of formula or their tautomeric forms, the attachment to the pyridine ring being in the 3- or 4-position, in which R', R" are the same or different and stand for hydrogen, halogen, or trifluoromethyl, hydroxy, C.sub.1 -C.sub.4 alkyl or alkoxy, nitro, or cyano groups. Alkylene stands for a straight or branched C.sub.1 -C.sub.8 carbon chain, which may be substituted by hydroxy or halogen, nitro or cyano groups. X stands for oxygen, for --S(O).sub.n -- where n stands for an integer from 0 to 2, or for .dbd.N--R.sub.1 where R.sub.1 is hydrogen or C.sub.1 -C.sub.4 alkyl. R stands for hydrogen or for one or more C.sub.1 -C.sub.4 alkyl or alkoxy, hydroxy, halogen, trifluoromethyl, cyano, carboxamido, sulfamoyl or nitro radicals. The present compounds are of value in the human and veterinary practice as selective serotonin receptor antagonists.
