Abstract
A practically efficient, environment friendly, and solvent free microwave-assisted protocol was developed for the synthesis of pyrazole-4-carboxylates. In this connection, we synthesized five new compounds (4a-4e) via microwave irradiation of a mixture of benzophenone hydrazones and acetoacetates in the absence of solvent. Short reaction time, easy workup and quantitative yield are the striking features of our protocol.
