Aroylhydrazines 2 reacted with 3‐benzylidene‐2,4‐pentanedione ( 1 ) to give 1‐aroyl‐3,5‐dimethyl‐1 H ‐pyrazoles 5 and benzaldehyde aroylhydrazones 6 . From the reaction of 3‐methoxymethylene‐2,4‐pentanedione ( 7 ) with aroylhydrazines 2 the unknown N ‐aroyl‐4‐acetyl‐1 H ‐pyrazoles 9 were exclusively isolated in good yields.
