| 摘要 |
A method in which a crude chlorinated product of a phenylpropanolamine, preferably prepared by reacting thionyl chloride with the phenylpropanolamine, is purified by contacting an aqueous solution of the crude product with carbon. The carbon-treated solution of the crude chlorinated product of a phenylpropanolamine is catalytically hydrogenated to the corresponding amphetamine derivative.
