Abstract

Synthesis of Some Piperazinylpyrazolo [3,4-b]pyridines as Selective Serotonin Re-Uptake Inhibitors.-Starting from 2,6-difluoropyridine (I), a number of piperazinylpyrazolo[3,4-b]pyridines (IX) and (X) are synthesized by directed ortho metallation and sequential intra-and intermolecular displacement of fluorine. The products are tested for their activities as selective serotonin re-uptake inhibitors. Compounds (IX) prove to be the most potent in the series and show a similar selectivity as fluoxetine. -(SHUTSKE, G. M.; ROEHR, J. E.; J.
