With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.118511-81-2,1-(Piperidin-4-yl)-1H-indole,as a common compound, the synthetic route is as follows.
PREPARATION 3 1-(1-Ethyl-piperidin-4-yl)-1H-indole To a solution of 1-piperidin-4-yl-1H-indole (0.6 g, 3 mmol) in 5 mL of dry ethanol was added anhydrous potassium carbonate (680 mg, 4.9 mmol). After stirring for 15 minutes at ambient temperature, ethyl p-toluenesulfonate (0.48 mL,4.5 mmol) was added. The reaction was heated under reflux for 24 hours with stirring, quenched with water, extracted with methylene chloride (2*), dried and evaporated to give a residue. The residue was chromatographed on silica gel with toluene/acetone (50:50) to yield 360 mg straw colored material (53% of theory).
118511-81-2, The synthetic route of 118511-81-2 has been constantly updated, and we look forward to future research findings.
