Synthesis and study of 1-(2-pyrimidinyl)-1H-pyrazolo[3,4-b]pyridine derivatives
New 1-(2-pyrimidinyl)-1H-pyrazolo[3,4-b]pyridine derivatives were obtained. The reactivity in reactions involving nucleophilic substitution of the chlorine atom by amino, arylamino, and hydrazino groups was investigated. Data from the IR, UV, and PMR spectra are presented.
