A number of 3-substituted 6-piperazinylpyrazolo[3,4-b]pyridines were synthesized from 2,6-difluoropyridine by directed ortho metallation and sequential intra- and intermolecular displacement of fluorine. Three derivatives with a cyano group in the 3-position showed activity as selective serotonin re-uptake inhibitors.
通过2,6-二氟吡啶通过定向邻位金属化和依次的氟内和分子内置换,合成了许多3-取代的6-哌嗪基吡唑并[3,4- b ]吡啶。在3位上带有氰基的三种衍生物显示出作为选择性5-羟色胺再摄取抑制剂的活性。
