synthetic targets (3). A number of known methods have been documented in the literature for the synthesis of pyrazolones. Most of these methods are based on the reaction of a hydrazine derivative with a ß-keto ester in a solvent under refluxing conditions (4). Recent developments include solid-phase synthesis of substituted pyrazolones from polymer-bounded ß-keto esters (5) and a two-step reaction of
