Abstract: One pot synthesis of 1-arylpyrazolo[3,4-d]pyrimidin-4-ones by the reaction of 5-amino-N-substituted-1H-pyrazole-4-carbonitrile with different lower aliphatic acids in the presence of POCl₃has been developed_. The structures of all the title compounds have been confirmed by IR, ¹H-NMR,^13C-NMR, and elemental analyses. Moreover, the structures of one of these compounds, 2c, was confirmed by single-crystal X-ray diffraction.

Keywords: POCl₃; one-pot; RCOOH; pyrazolo[3,4-d]pyrimidine
