Abstract

Typically, SNAr reactions at 4-chloro-2-methylthiopyrimidine are carried out employing DMF and sodium hydride under inert gas as well as prolonged reaction times. Herein, we describe a mild and rapid microwave-assisted synthesis to achieve 4-substituted 2-methylthiopyrimidnes from the corresponding chlorine precursor. Moderate to excellent yields were obtained in a green chemistry fashion requiring only few minutes of reaction time.
