focused on the preparation of new pyrazole derivatives, has led us to report here an original and simplified preparation of ethyl 3‐ethoxy‐1H‐pyrazole‐4‐carboxylate. This is based on the reaction of hydrazine monohydrochloride and diethyl 2‐(ethoxymethylene)malonate. Further transformations of this key compound allowed the preparation of the two possible iodinated isomers, namely, 3‐ethoxy‐4‐iodo‐ and
