An efficient one-pot synthesis of N-(1,3-diphenyl-1H-pyrazol- 5-yl)amides
摘要:
Abstractmagnified image A “one‐pot” method for the synthesis of N‐(1,3‐diphenyl‐1H‐pyrazol‐5‐yl)amides was developed by cyclization of benzoylacetonitrile (1) and phenylhydrazine in neat condition followed by acylation. The corresponding N‐(1,3‐diphenyl‐1H‐pyrazol‐5‐yl)amides were provided in good to excellent yields (70–90%). The significant advantages of the new synthetic method are excellent yields and simple work‐up procedure without isolation and purification of intermediary 5‐amino‐1,3‐diphenyl pyrazol (2). J. Heterocyclic Chem., (2010).
