With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.105191-12-6,6-Bromo-1H-indole-2-carbaldehyde,as a common compound, the synthetic route is as follows.
General procedure: To a mixture of 1H-indole-2-carbaldehyde (290 mg, 2.0 mmol, 1.0 eq.) and 1-(5-bromo-2-hydroxyphenyl)ethanone (430 mg, 2.0 mmol, 1.0 eq.) in ethanol (10 mL) was added piperidine (1 mL). The mixture was refluxed during 16 hours and then diluted with ethyl acetate after cooling to room temperature. The organic layer was washed with a 1M aqueous hydrochloric acid solution and water, dried over Na2SO4and then evaporated under reduced pressure. The residue was purified by silica gel flash-column chromatography (eluent: heptane/EtOAc, 90/10 to 80/20) to afford, after trituration with diethyl ether,7aas a red solid (160 mg, 23 %).
105191-12-6, The synthetic route of 105191-12-6 has been constantly updated, and we look forward to future research findings.
