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.
