Title:
METHOD FOR PRODUCING 1,3-BENZODIOXOLE DERIVATIVE
Document Type and Number:
WIPO Patent Application WO/2022/009911
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a novel method for producing a 1,3-benzodioxole derivative. The method comprises a novel chlorination reaction of a benzene ring which gives a good yield and a small amount of impurities and is industrially useful. A novel chlorination reaction of a benzene ring which gives a good yield and a small amount of impurities and is industrially useful was found by use of sulfuryl chloride in a novel method for producing a 1,3-benzodioxole derivative, and thus the invention was completed.
