An efficient method for the synthesis of new pyrazolo[3,4-d]pyrimidin-4- ones through heterocyclization reaction of 5-amino-l-phenyl- lH-pyrazole-4-carboxamides with aroyl halides under microwave irradiation in solvent-free condition is described. In comparison with classical conditions the reactions are faster and the yields are higher under microwave irradiation.
