An efficient synthesis of 21 new thiopurines being 2-substituted 6-(dialkylaminoalkylthio)-7-methylpurines, 6-substituted 2-(dialkylaminoalkylthio)-7-methylpurines, and 2,6-bis(dialkylaminoalkylthio)-7-methylpurines was reported. 2-Substituted 6-(dialkylaminoalkylthio) and 2,6-bis(dialkylaminoalkylthio) derivatives were obtained via direct S-dialkylaminoalkylation of the appro- priate purinethiones. The different reactivities of the dialkylaminalkylthio groups in positions 2 and 6 towards sodium alkoxides were the key processes in a few step synthesis of 2-(dialkylaminoalkylthio) derivatives from 2,6-bis(dialkylaminoalkylthio) derivatives.

Substituted 7-methyl-2- or 6-purinethiones were obtained in series of reactions by nucleophilic substitution with oxygen, chloro, and sulfur nucleophiles. Oxidation of the sulfur atom at position 6 or 2 in purinethiones to corresponding disulfides depended on the conditions of the reaction and oxidizing agent.
