The present invention provides a compound represented by the general formula: [wherein Ring A represents an optionally substituted 5- to 8-membered ring, Ring B represents a further optionally substituted 4- to 10-membered ring, Ring C represents a further optionally substituted
benzene ring, X1 represents
carbon atom, X2 represents a
carbon atom, an
oxygen atom, etc., W represents a
nitrogen atom, etc., Y11 represents a group represented by the formula CR2R3′ (wherein R2 represents a
hydrogen atom, a cyano group, a nitro group, etc., and R3′ represents a
hydrogen atom, a cyano group, a nitro group, etc., respectively), Y21 represents a group represented by the formula CR4R5′ (wherein R4 represents a
hydrogen atom, a cyano group, a nitro group, etc., and R5′ represents a
hydrogen atom, a cyano group, a nitro group, etc., respectively), etc., and R1 represents an
electron-withdrawing group, respectively. The formula represents a
single bond or a
double bond] or a salt thereof, which is useful as an
androgen receptor modulator.
