Title:
PROCESS FOR PRODUCING PYRROLE COMPOUND
Document Type and Number:
WIPO Patent Application WO/2010/098351
Kind Code:
A1
Abstract:
A process for producing a sulfonylpyrrole compound useful as a medicine, a process for producing an intermediate for use in the process, and a novel intermediate. The process for producing a sulfonylpyrrole compound (VIII) comprises reducing a compound (III), subsequently hydrolyzing the compound to obtain a compound (IV), sulfonylating the compound (IV) to obtain a compound (VI), and aminating the compound (VI) to thereby produce the compound (VIII).
