Microwave synthesis of 1-aryl-1H-pyrazole-5-amines
2019
Abstract A microwave-mediated synthesis of 1 H -pyrazole-5-amines utilizing 1 M HCl at 150 °C was developed in order to provide products in a matter of minutes with minimal purification. Most reactions are complete in only 10 min and can be isolated via a simple filtration without the need for further purification by column chromatography or recrystallization. This method tolerates a range of functional groups and can be performed on milligram to gram scales.
