With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.10241-97-1,5-Methyl-1H-indole-2-carboxylic acid,as a common compound, the synthetic route is as follows.
General procedure: To a solution of 5-methyl-1H-indole-2-carboxylic acid (20) (263mg, 1.50mmol) in THF (7mL) were added 2-(piperidin-4-yl)ethanol (213mg, 1.65mmol), 1-hydroxybenzotriazole (HOBt, 101mg, 0.750mmol), and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDAC) hydrochloride (316mg, 1.65mmol), followed by stirring at room temperature for 14h. The reaction mixture was partitioned between ethyl acetate and 0.5M aqueous hydrochloric acid. The organic layer was washed with saturated aqueous sodium hydrogen carbonate solution and saturated aqueous sodium chloride solution, dried over anhydrous sodium sulfate, and then concentrated in vacuo. The residue was recrystallized from ethyl acetate/acetonitrile (5mL/2mL) to give 3 (365mg, 85.0percent) as a beige powder.
10241-97-1, As the paragraph descriping shows that 10241-97-1 is playing an increasingly important role.
