The present invention provides a production method of a sulfonylpyrrole compound useful as a pharmaceutical product, a production method of an intermediate used for the method, and a novel intermediate. The present invention relates to a method of producing sulfonylpyrrole compound (VIII), which includes reducing compound (III) and hydrolyzing the reduced product to give compound (IV), subjecting compound (IV) to a sulfonylation reaction to give compound (VI), and subjecting compound (VI) to an amination reaction.

organic dyes and microbial pollutants. Adsorption performance of multiple mixtures of basic and acidic dyes by P3C@CaO–HCN was investigated and optimized using a three-level Box–Behnken design of experiment (BBD-DOE). The quadratic Box–Behnken polynomial equation showed the best fit with experimental adsorption capacities of crystal violet (CV), methylene blue (MB), and methyl orange (MO) model dyes. The
