The synthesis of a number of new 6-alkoxy-8,9-(disubstituted)purines has been accomplished by the cyclization of the corresponding intermediate 5-amino-4-chloro-6-(alkylamino)pyrimidines promoted by alkoxides and various N,N-dimethyl amides, where the latter act as solvent-reagents. By this three-component condensation reaction we are able to introduce an alkyl group in the 8 position of the purine ring with the concomitant nucleophilic replacement of the 6-chloro group with an alkoxy moiety.
