1-Methyl-3-phenylpyrazolo[4,3-b]pyridines were synthesized via a cyclization reaction of 1-methyl-4-amino-3-phenylpyrazoles 8 with ethyl acetoacetate. Optimization of this series of compounds resulted in CRF 1 antagonists with subnanomolar binding affinity. Compounds bearing a polar group such as methoxy or hydroxy were also found to be very active.
Synthesis of 3-phenylpyrazolo[4,3-b]pyridines via a convenient synthesis of 4-amino-3-arylpyrazoles and SAR of corticotropin-releasing factor receptor type-1 antagonists

3-Phenylpyrazolo[4,3-b]pyridines were synthesized via a cyclization of 4-amino-3-phenylpyrazoles 11-13 with ethyl acetoacetate. These compounds were found to be potent CRF1 antagonists. The 2-alkylpyrazolo[4,3-b]pyridines were more polar but le
