Abstract Pyrazolopyrimidinone compounds have many biological activities and been widely used due to the similar structure of purines in organisms. However, the traditional synthetic methods suffered from several drawbacks, such as acylation and cyclization. Herein, one pot cyclization of 1H-pyrazolo[3,4-d]pyrimidin-4(5H)-one was developed by one pot conversion of 5-amino-4-cyano-pyrazole and aromatic aldehydes in the presence of sodium hydroxide using water as media. The reaction was carried out under the conditions of easily available raw materials, simple operation, and showed good tolerance to various functional groups.

Key words: one pot conversion, pyrazolo[3,4-d]pyrimidin-4(5H)-one, sodium hydroxide, green solvent, water
