Title:
METHOD FOR PRODUCING ARYLSULFONIC ACID ESTER COMPOUND
Document Type and Number:
WIPO Patent Application WO/2020/218316
Kind Code:
A1
Abstract:
Provided is a method for producing an arylsulfonic acid ester compound which comprises: a first step, in which an arylsulfonic acid of formula (1) (wherein A is an aromatic group, B is an aromatic group substituted by a halogen atom, n is an integer satisfying 1≤n≤4, and q is an integer satisfying 1≤q) is reacted with a halogenating reagent in the presence of a DMF catalyst to produce a halide of formula (2) (wherein X is a halogen atom and A, B, n, and q are as defined above), wherein a solution of the arylsulfonic acid in DME or in diethylene glycol diethyl ether is dropped into the halogenating reagent; and a second step, in which the obtained halide is reacted at 15°C or lower with an alcohol in an organic solvent in the presence of a base of formula (3) (wherein the R moieties each independently represent an alkyl group optionally containing a heteroatom, but the two R moieties may be bonded to each other to form a ring structure).
