Direct C3-arylation of 1H-pyrazolo­[4,3-b]­pyridines and direct C3-arylation of 2H-pyrazolo­[4,3-b]­pyridines in water has been developed. A new protocol for a sequential C3-arylation procedure on a mixture of 1H- and 2H-pyrazolo­[4,3-b]­pyridines followed by in situ PMB cleavage has also been achieved. This procedure led to unprotected (NH) C3-arylated 1H-pyrazolo­[4,3-b]­pyridines in good yields.
