Reactivity of 7-(2-Dimethylaminovinyl)pyrazolopyrimidines: Synthesis of Pyrazolopyridopyrimidine Derivatives as Potential Benzodiazepine Receptor Ligands. 2.

A series of pyrazolopyridopyrimidin-6-ones was obtained by reaction of ammonium acetate with ethyl 7-dimethylaminovinylpyrazolopyrimidine-6-carboxylates and these had been prepared from ethyl 7-methylpyrazolopyrimidine-6-carboxylates by reaction with dimethylformamide dimethylacetat.Under these conditions the compounds bearing a 2-hydroxy group were also O-alkylated.During the preparation of the ethyl 2-hydroxy-7-methyl-3-phenylpyrazolopyrimidine-6-carboxylate the corresponding 5-methyl isomer was isolated and identified.
