摘要： The present invention provides a method for producing a sulfonate ester efficiently and in high yield.
The present invention is an invention of a method for producing a sulfonate ester compound, which comprising reacting:
(a) a compound having a sulfo group (-SO 3 H); and
(b) a compound having a group represented by the general formula [1]:

-OR 1 [1]

[wherein, R 1 represents a sulfonyl group represented by the general formula [2]:

-SO-R 2 [2]

(wherein, R 2 represents a halogen atom, a haloalkyl group, an alkoxy group, or an optionally substituted alkyl group or an optionally substituted aryl group) or an acyl group represented by the general formula [3]:

(wherein, R 3 represents an optionally substituted alkyl group or an optionally substituted aryl group)];
in the presence of an organic base which is capable of forming a salt with said sulfo group.
