Aminodifluorosulfinium tetrafluoroborate salts were found to act as efficient deoxofluorinating reagents when promoted by an exogenous fluoride source and, In most cases, exhibited greater selectivity by providing less elimination byproduct as compared to DAST and DeoxoFluor. Aminodifluorosulfinium tetrafluoroborates are easy handled crystalline salts that show enhanced thermal stability over dialkylaminosulfur trifluorides, are storage-stable, and unlike DAST and Deoxo-Fluor do not react violently with water.

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.
