To a solution of 5-bromomethyl-3-(4-methoxyphenyl)-[1,2,4]thiadiazole (0.048 g, 0.15 mmol) in DMF (2 ml) was added 2,6-difluoro-3-hydroxybenzamide (0.027 g, 0.15 mmol) and potassium carbonate (0.76 g, 0.55 mmol). The reaction mixture was stirred at 25° C. for 12 h under nitrogen atmosphere. After the completion of the reaction (TLC monitoring), the reaction mixture was evaporated to dryness under vacuum, added 30 ml water and extracted with ethyl acetate (3×20 ml). The combined organic layer was dried over Na2SO4, filtered and concentrated under vacuum. The crude residue was purified over silica gel (100-200 M, 50% EtOAc-Hexane) to get the desired product (0.011 g, 30%).
