    摘要: Process for the manufacture of N-(2-halogenoethyl)-N-(2-hydroxy2-phenylethyl)amines, known intermediates in manufacture of the anthelmintic tetramisole. In one alternative, process comprises reacting N-(2-hydroxyethyl)-N-(2-hydroxy-2-phenylethyl)amine with a halogenating agent, e.g., thionyl chloride, to give N-(2halogenoethyl)-N-(2-halogeno-2-phenylethyl)amine salt, and reacting latter compound with water to give said monohalogeno compound. In another alternative, the isomeric N-(2hydroxyethyl)-N-(2-hydroxy-1-phenylethyl)amine is reacted with halogenating agent to give N-(2-halogenoethyl)-N-(2-halogeno-1phenylethyl)amine derivative, and reaction of latter with water gives said monohalogeno derivative. In another alternative, a mixture of the two said dihydroxy compounds is used as starting material. Conversion of the two dihalogeno derivatives to the same monohalogeno derivative proceeds, apart from exceptional circumstance, via an aziridine derivative.
