5-Chloroindole - Reference Information
| introduction | 5-chloroindole is an indole compound. Indole compounds widely exist in nature. Many indole containing substituents on benzene ring have biological activity. Indole and its derivatives are also important chemical raw materials and are widely used in many fields such as medicine, pesticides, dyes, food and spices. |
| Uses | 5-chloroindole is a halogen-substituted indole used to prepare neuroactive compounds, such as atypical antipsychotics. 5-chloroindole has been shown to reduce serotonin levels in the brainstem and telencephalon. |
| preparation | 2eq binaborate pinacyl ester, 2.5eq potassium fluoride, 3ml ethanol and 0.2 mmol2-nitro 5-chlorocinnamic acid are added into a pressure-resistant reaction tube containing 3mL methanol, filled with nitrogen, stirred in an oil bath at 100 ℃ for 12h, followed by TLC and GC during the reaction to determine the specific reaction time. After cooling to room temperature, adding ethyl acetate and mixing thoroughly, the mixed solution is diluted with ethyl acetate, filtered and washed with ethyl acetate. After concentration, the organic phase was combined, and the eluent with petroleum ether: ethyl acetate = 50:1 was used to obtain the product through the column with a yield of 78%. |
