실험 절차

3-Fluoro-4-[5-benzoyl-1,4-dimethyl-1H-pyrrol-2-ylmethyl]aniline (1.0 g, 3.1 mmol) [prepared as described in Example 1] was dissolved in pyridine (10 ml) and the solution was cooled to -5° C. Methanesulfonyl chloride (0.39 g, 3.4 mmol) was added and after 1 h the reaction mixture was poured into 1 M HCl/ice/water and extracted with ethyl acetate. The organic layer was washed with water, dried over sodium sulfate and concentrated to dryness. The residue was crystallized from methylene chloride-methanol to give N-(3-fluoro-4-[5-benzoyl-1,4-dimethyl-1H-pyrrol-2-ylmethyl]phenyl}-methanesulfonamide (775 mg, 62%) as a solid, mp 165-167° C.
