Abstract
3-Methyl-1-phenylpyrazolin-5-one (1) was reacted with arylmethylenecyanoacetic
acid ethyl ester (2) to give 4-[2-cyano-2-ethoxycarbonyl-1-
(atyl)ethyl]-3-methyl-1-phenylpyrazolin-5-one. However, when the ethanolic
solution of compound (3) was treated with piperidine, arylmethylidenebis-
(5-hydroxpyrazole) (4) was produced.
