| Abstract: | Treatment of 3-(or-hydroxybenzyl)pyrazolo1,5-a]pyridines with trifluoroacetic acid in dichloromethane resulted in the formation of pyrazolo1,5-a]pyridines, bisα-(pyrazolo1,5-a]pyrid-3-yl)benzyl] ethers, and phenylbis(pyrazolo1,5-a]pyrid-3-yl)methanes, depending upon the presence or absence of the substituents at the 2- and/or 4-positions and the reaction conditions employed. |
