Reaction Steps

A solution of 7.9 g (36.5 mmol) of 1-(5-ethyl-1-phenyl-1H-pyrazol-4-yl)-ethanol in 100 mL THF was stirred at rt over 24 g of activated MnO2 for 23 h. The mixture was filtered through Celite and concentrated to give 1-(5-ethyl-1-phenyl-1H-pyrazol-4-yl)-ethanone (7.71 g). ESI MS m/z 215 [C13H14N2O+H]+.
