Participants

Reaction Steps

To a solution of 3-(2-(benzyloxy)-4-chlorophenyl)-5-(bromomethyl)-1,2,4-thiadiazole (0.33 g, 0.83 mmol) in DMF (10 ml) was added 2,6-difluoro-3-hydroxybenzamide (0.13 g, 0.75 mmol) and potassium carbonate (0.403 g, 2.92 mmol). The reaction mixture was stirred at room temperature for 16 h under nitrogen atmosphere. After the completion of the reaction (TLC monitoring), the reaction mixture was evaporated to dryness under vacuum, added 25 ml water and extracted with ethyl acetate (3×25 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 (0.123 g, 30%).
