Uses | 3-acetylpyrrole is an organic intermediate, and it has been reported in the literature that it can be used to prepare IL-1 inhibitors and TRPA1 regulators. |
Preparation | 3-acetylpyrrole can be prepared from pyrrole. Pyrrole (10.0g) was added to a fully stirred suspension of NaOH (17.9g, 447.3 mmol) in 10 mL of dichloromethane. The reaction mixture was cooled to 0°C. Stir the reaction mixture for 10 minutes. A solution of benzenesulfonyl chloride (31.6g) in 2 mL of dichloroethane was added dropwise to the reaction mixture. When the addition is complete, let the reaction mixture reach room temperature. Let the reaction mixture be stirred overnight. Pour 60 mL H2O to quench the reaction. Separation of organic layers. The water layer was extracted with dichloromethane (3 × 60 mL). Wash the combined organic extract with water to neutral. The combined organic extracts were dried with Na2SO4. Remove the solvent. The residue was purified by recrystallization to obtain 3-acetylpyrrole. |
