Abstract

Abstract [1, 2, 4] Triazolo [1, 5-a] pyridines without substituents 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, 69451 Weinheim, Germany, 2005)
