(+)-N-Ethyl-α-methyl-m-[trifluoromethyl]phenethylamine - Preparation Method
Open Data Verified Data
- at 0 ° C., chlorosulfonic acid was added to a solution of trifluorotoluene and paraformaldehyde, and the mixture was stirred to obtain 3-chloromethyltrifluorotoluene. This was added to a solution of sodium cyanide in water and ethanol, and the reaction was processed to give 3-trifluoromethylbenzene acetonitrile. The compound was reacted with potassium hydroxide, water, and ethanol with heating. Ethanol was distilled off, neutralized with acid, and recrystallized to give 3-fluoromethylphenylacetic acid. A solution of methyl iodide in diethyl ether was added to the solution of diethyl ether and lithium under nitrogen and stirring, and the reaction was carried out. Then, the reaction was carried out by adding a solution of 3-fluoromethylphenylacetic acid in diethyl ether to a solution of the obtained compound and an excess of ethylamine in methanol. After standing, the reaction was carried out by adding potassium borohydride. Acidified to acidic, the aqueous layer was basified and extracted with dichloromethane. Dry hydrogen chloride was introduced into methylene chloride to be acidic, and the precipitated solid was recrystallized to obtain fenfluramine hydrochloride.
- or the reaction was carried out with magnesium turnings and an ether solution of M-bromotrifluorotoluene, followed by reflux. A solution of propylene oxide in diethyl ether was added dropwise with stirring, and the mixture was stirred. Into the mixture of concentrated hydrochloric acid and ice water, the compound is obtained by treatment, the compound is dissolved in ether, and the solution of sodium chromate is added dropwise under stirring to react, and the compound obtained by treatment and the methanol solution of excess ethylamine, after standing, potassium borohydride was added for reaction. Acidified to acidic, the aqueous layer was basified and extracted with dichloromethane. Dry hydrogen chloride was introduced into methylene chloride to be acidic, and the precipitated solid was recrystallized to obtain fenfluramine hydrochloride.
