Reaction Steps

To a stirred solution of 5-Bromo-pyridin-2-ylamine (100 mg, 0.578 mmol) in dry THF was added acetic anhydride (70.25 mg, 0.693 mmol). The reaction mixture was stirred at 20° C. for 12 hrs. THF was distilled out and to it was added ethyl acetate. The organic layer was washed with saturated NaHCO3 solution and dried over anhy sodium sulphate. Removal of the solvent afforded N-(5-Bromo-pyridin-2-yl)-acetamide (100 mg, 80%). This was carried to next step without further purification.
