1H-Pyrazolo[3,4-b]pyridine-3-carboxylicacid - Reference Information
| Use | 1H-pyrazolyl [3,4-B] pyridine-3-carboxylic acid is a carboxylic acid derivative, it can be used as an intermediate in the synthesis of medicine and in the experimental research of medicine. |
| preparation | at room temperature, A mass of 2-chloro-3-acetylpyridine was added to the condenser tube and an electrically stirred three-necked flask, and hydrazine hydrate was added as a solvent. The reaction was stirred in organic solvent for 1 hour, heated to reflux overnight, and the reaction progress was detected by thin layer chromatography. When the reaction was finished, the temperature was stopped, and the system was cooled to room temperature, then purified water and dichloromethane were added, the reaction solution was extracted, and the organic phase was collected after standing and stratification, and the aqueous phase was washed many times. After the organic phase was combined, anhydrous sodium sulfate was added to dry, and the organic phase was concentrated and purified by silica gel column chromatography, the compound 1H-pyrazolyl [3,4-B] pyridine-3-carboxylic acid was obtained. |
