Reaction Steps

To a solution of 3-(4-benzyloxyphenyl)-5-bromomethyl-[1,2,4]thiadiazole (0.04 g, 0.11 mmol) in DMF (2 ml) was added 2,6-difluoro-3-hydroxybenzamide (0.017 g, 0.10 mmol) and potassium carbonate (0.53 g, 0.39 mmol). The reaction mixture was stirred at 25° C. overnight under nitrogen atmosphere. After the completion of the reaction (TLC monitoring), the reaction mixture was evaporated to dryness under vacuum, added 20 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, 40% EtOAc-Hexane) to get the desired product (0.025 g, 50%). MS ES+ (454.13).
