ABSTRACT:
A process for preparing a cysteamine-S-substituted compound involves reacting ethyleneimine or ethyleneimine derivatives with a thiosulfate or thiophosphate in the presence of a cation exchanger of a free type. Use of the cation exchanger of a free type in this reaction allows preparation of the cysteamine-S-substituted compound with an amazingly high purity in a high yield.
