A Two Hour Synthesis of the Anti-Parkinson Drug Safinamide Methanesulfonate

Abstract

AbstractThe critical moment of the COVID-19 outbreak requires a real-time supply of therapeutic agents. Thus, time economy in the synthesis of biologically active compounds has become increasingly decisive. In this work, we developed a two hour synthesis of the anti-Parkinson drug safinamide methanesulfonate in four steps with a 64% overall yield. Microwave irradiation was used in the first three steps in a one-pot fashion. In fact, the protocol can provide safinamide free base in one hour without a chromatographic purification step. Also, green solvents such as methanol and ethyl acetate are used.
