PROCESS FOR PRODUCING SULFONE DERIVATIVE

摘要

A process for producing a sulfone derivative represented by the general formula R-W-S(O)2-X-Y-L2 (IIIa) (wherein R represents an optionally substituted cyclic hydrocarbon group, etc.; W represents a bond or an optionally substituted divalent chain hydrocarbon group; X represents an optionally substituted divalent chain hydrocarbon group; Y represents -N(R5)-, -CO-, -S(O)-, -S(O)¿2?-, -CH2-, or a bond; and L?2¿ represents hydrogen, hydroxy, or optionally substituted alkoxy) or a salt thereof, characterized by reacting a sulfinic acid derivative represented by the general formula R-W-S(O)¿2?-M (I) (wherein R and W are the same as defined above; and M represents hydrogen, an alkali metal, or an alkaline earth metal) or a salt thereof with a compound represented by the general formula L?1-X-Y-L2¿ (IIa) (wherein X, Y, and L2 are the same as defined above; L1 represents a leaving group; and R5 represents hydrogen, etc.) or a salt thereof.
