The invention relates to a method for synthesizing [1,2,3]triazole[1,5-a]pyridines compound through non-catalyst N-N coupling reaction. The invention discloses an efficient method for synthesizing a product at one step without using a catalyst under a mild condition from a 2-pyridylamine compound and nitroso tert-butyl ester as a mild nitrogen atom source. The method is free from the catalyst, thereaction step is reduced, the condition is extremely mild, the efficiency is high, and the later modification can be performed on the biological active molecular, thereby facilitating the industrialproduction of [1,2,3]triazole[1,5-a]pyridines compound.

The lithiation reactions of 1,2,3-triazolopyridine (1) to give the 7-lithio-derivative (4; R = Li), and of its 7-methyl derivative (16) to give the 7-lithiomethyl compound, are described.These lithium derivatives react with electrophiles, notably a
