Synthesis of 4-aminopyrazolo[3,4-d]pyrimidine derivatives from 5-acetyl-6-amino-4-methylsulfanyl- or 5-acetyl-6-amino-4- methylsulfonylpyrimidines

Diacetyl ketene N,S-acetal was used for the synthesis of 5-acetyl-6-amino-4-methylsulfanylpyrimidines substituted at the exocyclic nitrogen atom, which were further oxidized with m-chloroperbenzoic acid to the corresponding methylsulfonylpyrimidines. Reac
