Brief introduction of 56839-43-1

As the paragraph descriping shows that 56839-43-1 is playing an increasingly important role.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.56839-43-1,1-(4-Ethylphenyl)-2-methyl-3-(piperidin-1-yl)propan-1-one hydrochloride,as a common compound, the synthetic route is as follows.

b) When eperisone hydrochloride is used as an organic amine compound: Indomethacin (358 mg, 1 mmol) and eperisone hydrochloride (395 mg, 1 mmol) were dissolved in methanol (3 mL), and 1N aqueous sodium hydroxide solution (1 mL) was added. The solution was concentrated under reduced pressure, 2-propanol (10 mL) was added, and the mixture was again concentrated under reduced pressure. 2-Propanol (10 mL) was added to the residue, and the resulting precipitate was filtered off. The filtrate was concentrated under reduced pressure to give an indomethacin-eperisone salt as a yellow starch syrup-like viscous liquid. This product showed an infrared absorption spectrum similar to the above-mentioned a)., 56839-43-1

As the paragraph descriping shows that 56839-43-1 is playing an increasingly important role.
