A microwave-mediated synthesis of 1H-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 chromatog. or recrystallization This method tolerates a range of functional groups and can be performed on milligram to gram scales. In the experiment, the researchers used many compounds, for example, 3-Oxo-3-phenylpropanenitrile(cas: 614-16-4COA of Formula: C9H7NO)
3-Oxo-3-phenylpropanenitrile(cas: 614-16-4) has been used in the synthesis of substituted naphtho[1,8-bc]pyrans. It was also used as building block in the preparation of 4H-pyrans, 2-pyridones, furans and carbocyclics.COA of Formula: C9H7NO
