appropriately substituted benzaldehyde or phenyl acetaldehyde, in acidic methoxyethanol. Analogues 21-23 were synthesized via nucleophilic displacement of 2,6-diamino-8-(chloromethyl)purine with the appropriate anilines or 2-naphthalenethiol. The compounds were evaluated as inhibitors of pcDHFR and tgDHFR with rat liver (rl) DHFR as the mammalian reference enzyme. Compound 11, the 3',4'-dichlorophenyl
