  • Patent number: 6323197
    Abstract: The invention concerns compounds of formula (I), in which R1, R2, R3 and R4 mean hydrogen or different substituents; X means hydrogen or halogen; Y means C1-6 alkoxy or X and Y together mean —O—(CH2)n—O—; n means 1, 2 or 3; and A together with nitrogen forms a saturated or unsaturated five-member heterocycle which can contain between 1 and 3 nitrogen atoms and/or an oxygen atom and/or one or two carbonyl groups. Owing to their non-competitive inhibiting of the AMPA receptors, these compounds can be used as medicaments for treating diseases of the central nervous system.
