Acid-Catalyzed Reactions of 3-(Hydroxymethyl)- and 3-(1-Hydroxyethyl)pyrazolopyridines

Treatment of 3-(hydroxymethyl)pyrazolopyridines with trifluoroacetic acid in refluxing dichloromethane led to the formation of bis(pyrazolopyrid-3-yl)methanes or bis pyrid-3-yl)>methyl ethers depending upon the concentration of trifluoroacetic acid.In contrast, similar treatment of 3-(1-hydroxyethyl)pyrazolopyridines gave a mixture of 3-vinylpyrazolopyridines and 1,3-bis(pyrazolopyrid-3-yl)-1-butenes.
