Abstract
An easy route to the synthesis of 2-substituted-7-azaindole derivatives has been developed. The carbinol intermediate dissolved in DMF undergoes cyclization upon treatment with sodium hydride, trifluoroacetic anhydride, and trifluoroacetic acid at 120 °C in a straightforward and one-pot step. An alternative methodology using (CF3SO2)2O in acetonitrile in basic media followed by the addition of CF3COOH affords the expected 2-substituted azaindole in best yields.
