Procedure

To a solution of 5-Bromo-2-bromomethyl-4-(4-methoxy-phenyl)-thiazole (0.50 g, 1.37 mmol) in 5 ml of anhydrous DMF was added 2,6-Difluoro-3-hydroxy-benzamide (0.23 g, 1.37 mmol) and potassium carbonate (0.75 g, 5.43 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 (30:70) as the eluent to provide the title compound (0.30 g, 48%).
