Potent and selective inhibitors of tumor necrosis factor-α converting enzyme (TACE) were discovered with several new heterocyclic P1′ groups in conjunction with cyclic β-amino hydroxamic acid scaffolds. Among them, the pyrazolopyridine provided the best o
FLUOROCARBON DERIVATIVES OF NITROGEN. PART 11. SYNTHESIS OF SOME 2-(TRIFLUOROMETHYL)IMIDAZOPYRIDINES FROM TRIFLUOROACETONITRILE

3-(t-Butoxycarbonyl)-2-(trifluoromethyl)imidazopyridine, prepared from trifluoroacetonitrile and pyridinium t-butoxycarbonylmethylide, reacts smoothly with trifluoroacetic acid to provide 2-(trifluoromethyl)imidazopyridine-3-carboxylic acid, which gives 2-(trifluoromethyl)imidazopyridine when heated. 3-Cyano-2-(trifluoromethyl)imidazopyridine can be obtained via treatment of trifluoroacetonitrile with pyridinium cyanomethylide, which is sufficiently reactive to effect nucleophilic displacement of fluorine from pentafluoropyridine under mild conditions pyridinium cyano(tetrafluoro-4-pyridyl)methylide>.
Reaction of Pyridinium t-Butoxycarbonylmethylide with Trifluoroacetonitrile

Pyridinium t-butoxycarbonylmethylide (I), generated by treatment of N-(t-butoxycarbonymethyl)pyridinium perchlorate with sodium hydride in acetonitrile, reacts with trifluoroacetonitrile to give 3-(t-butoxycarbonyl)-2-(trifluoromethyl)-imidazopyridine (II), pyridinium 4,5-dihydro-4-oxo-2,6-bis(trifluoromethyl)pyrimidin-5-ylide (III), and N-pyridinium perchlorate (IV).Formation of the last two products, plus the fact that when treated with sodium hydride the perchlorate (IV) yields the imidazopyridine (II), provides powerful evidence in support of a stepwise mechanism for the 1,3-dipolar cycloaddition involved in formation of the imidazopyridine nucleus in (II).
