Abstrakt: It has been shown that S-ß-aminoalkyl derivatives of 2-mercaptopyrimidine and 2-mercapto-4, 6-diaminopyrimidine, containing primary and secondary amino groups, undergo S ? N rearrangement in neutral or weakly alkaline solution, with the formation of the corresponding aminothiols. In the case of derivatives of 2-mercapto-4, 6-diaminopyrimidine, however, the S ? N rearrangement proceeds more slowly, apparently as a result of the difficulty of formation of the intermediate cyclic compound.
