실험 절차

To a solution of the compound (1.0 g, 2.0 mmol) of Example 1 in dichloromethane (10 mL), Dess-Martin reagent (1.3 g, 3.0 mmol) was added at 0° C. The reaction temperature was raised to room temperature, and after the mixture was further stirred for 1 hour, it was diluted with ethyl acetate and the organic layer was washed with an aqueous sodium hydrogencarbonate solution, an aqueous sodium thiosulfate solution, water and saturated brine. After the solution was dried with sodium sulfate, it was filtered and the solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=1:1) to give 1-[4-chloro-2-(trifluoromethyl)phenyl]-2-methyl-N-[4-(methylsulfonyl)phenyl]-5-(2-oxoethyl)-1H-pyrrole-3-carboxamide (0.85 g, 85%).
