Orally active Hsp90 inhibitors are of interest as potential chemotherapeutic agents. Recently, fully synthetic 8-benzyladenines and 8-sulfanyladenines such as 4 were disclosed as Hsp90 inhibitors, but these compounds are not water soluble and consequently
An efficient one-pot synthesis of 6-alkoxy-8,9-dialkylpurines via reaction of 5-amino-4-chloro-6-alkylaminopyrimidines with N,N-dimethylalkaneamides and alkoxide ions

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.
