実験手順

To a solution of the above (1-[4-chloro-2-(trifluoromethyl)phenyl]-5-methyl-4-{[4-(methylsulfonyl)phenyl]carbamoyl}-1H-pyrrol-2-yl)acetic acid (30 mg, 0.518 mmol) in DMF (0.58 mL), 1-hydroxybenzotriazole monohydrate (18 mg, 0.12 mmol) and hydrochloric acid 1-(3-dimethyl-aminopropyl)-3-ethylcarbodiimide (23 mg, 0.12 mmol) were successively added, and the mixture was stirred at room temperature for 1 hour. Thereafter, a 2M dimethylamine/THF solution was added to the mixture, and the mixture was stirred overnight. After the reaction, it was diluted with ethyl acetate, and the organic layer was washed with 1M hydrochloric acid, water and saturated brine. Thereafter, it was dried with sodium sulfate, filtration was carried out, and the solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography to give the title compound (17 mg, 54%).
