Description

General description

Ethyl 3-methylpyrazole-5-carboxylate can be prepared by reacting ethyl acetylpyruvate and hydrazine.

Application

Ethyl 3-methylpyrazole-5-carboxylate may be used to synthesize the following ligands:

• potassium salt of new dihydrobis(3-carboxyethyl-5-methylpyrazolyl)borate (Bp^COOEt,Me)
