Procedure
To a solution of 5-Bromo-2-bromomethyl-4-(3-methoxy-phenyl)-thiazole (0.80 g, 2.20 mmol) in 5 ml of anhydrous DMF was added 2,6-Difluoro-3-hydroxy-benzamide (0.38 g, 2.20 mmol) and potassium carbonate (1.06 g, 7.70 mmol). The reaction mixture was stirred at 25° C. for 24 h under nitrogen atmosphere. The reaction mixture was evaporated to dryness under reduced pressure and the residue was purified by column chromatography on silica (60-120 M) using ethyl acetate/hexane (50:50) as the eluent to provide the title compound as white solid (0.50 g, 49%).
