Use | intermediate of vitamin B6. |
production method | is obtained by esterification of α-alanine. Anhydrous ethanol and α-alanine were put into a reaction pan, and dry hydrogen chloride gas was introduced at room temperature to saturation. After the reaction solution was all clear, the reaction mixture was heated and refluxed for 4H. Distilled amount of ethanol to dryness. DL-alanine ethyl ester hydrochloride was obtained. |
