To the solution of 2,5-Dibromo-pyridin-3-ylamine (8.6 g, 34.12 mmol) in 50 ml of DCM was added triethylamine (5.3 ml, 37.53 mmol). Cooled the reaction mixture to 0° C. To this added the solution of 2-benzyloxy acetyl chloride (7.45 g, 40.95 mmol) in 35 ml of DCM. The reaction mixture was stirred at 25° C. for 12 hr. After the completion of the reaction mixture (TLC monitoring), the reaction mixture was evaporated to dryness under reduced pressure. The residue was purified by column chromatography on silica (60-120 M) using ethyl acetate/hexane (10:90) as the eluent to provide the title compound (3.2 g, 24.17%).
