An object of the present invention is to provide a novel AMPA receptor potentiator. A compound represented by the following formula (I) or a salt thereof:
wherein in formula (I)
R1 represents
(1) a halogen atom, or (2) cyano group, or the like;
Ra and Rb each independently represent a hydrogen atom or C1-4 alkyl;
L represents a bond, or a spacer in which the number of atoms in the main chain is 1 to 8;
Ring A represents
(1) a non-aromatic carbon ring of 4-8 carbon atoms, or
(2) a 4- to 8-membered non-aromatic heterocycle
either of which is optionally substituted with 1 or more substituents selected from
(a) halogen atoms, and (b) cyano group; and
Ar represents
a substituted phenyl group, or
optionally substituted 5- or 6-membered aromatic heterocyclic group.
