Reaction Steps

In a 100 ml 3 necked round bottom flask, 2-(1H-1,2,3-triazol-1-yl)pyridine (2 g) was taken in dry THF (2 ml) under nitrogen. n-Butyl lithium (2.3 ml) was added at −78° C. and stirred for 5 minutes, then bromine (1.86 ml was added dropwise to the above reaction mixture. Reaction mixture was stirred at −78° C. for 1 hour. TLC was checked no starting material and the reaction mixture was quenched with saturated ammonium chloride (50 ml) and ethyl acetate was added. The organic layer was washed with sodium bisulphate, brine, dried and concentrated. The crude product was purified by column chromatography using pet ether & ethyl acetate as eluent to give compound 2-(5-bromo-1H-1,2,3-triazol-1-yl)pyridine as yellow solid.
