New method for the general synthesis of [1,2,4]triazolo[1,5-a]pyridines
[1,2,4]Triazolo[1,5-a]pyridines without substituants on the 2-position have been prepared from 2-aminopyridines by cyclization of N-(pyrid-2-yl) formamidoximes with trifluoroacetic anhydride. Triazoles substituted at any position on the pyridine ring may be prepared in good yields and under mild reaction conditions. Wiley-VCH Verlag GmbH & Co. KGaA, 2005.
