Abstract:

Synthesis of hardly available 2-alkylsemicarbazides and their hydrochlorides from semicarbazide hydrochloride has been developed. This general and efficient protocol is based on preparation of acetone semicarbazone, its N2-alkylation in the presence of sodium hydride, and hydrolysis under mild conditions.

Keywords: Semicarbazides, semicarbazones, alkylation, hydrolysis
