Reaction Steps
Methyl 2-chloropyrimidine-5-carboxylate (0.863 g, 5.0 mmol), N,N-diethylethanamine (0.697 ml, 5.00 mmol) and 1-methylpiperazine (0.565 ml, 5.09 mmol) were suspended in 2-propanol (10.00 ml) and sealed into a microwave tube. The reaction was heated to 100° C. for 10 mins in the microwave reactor and cooled to room temperature. The precipitate was collected by filtration, washed with EtOH (5 mL) and dried under vacuum to afford methyl 2-(4-methylpiperazin-1-yl)pyrimidine-5-carboxylate (0.405 g, 34.3%) as a white solid, which was used without further purification.
