Procedure

To a solution of 3-[5-bromo-4-(4-methoxy-phenyl)-thiazol-2-ylmethoxy]-2,6-difluoro-benzamide (0.20 g, 0.043 mmol) in 5 ml of anhydrous DMF was added 4-tributylstannyl thiazole (0.16 g, 0.43 mmol) and degassed the reaction mixture for 10 minutes. Tetrakis(triphenylphosphine) palladium (0) (0.05 g, 0.043 mmol) was then added and the reaction mixture was heated at 120° C. for 12 h under the nitrogen atmosphere. Then reaction mixture was cooled to room temperature added water (25 mL) and extracted the compound with ethyl acetate (3×50 mL). The combined organic layers were dried over anhydrous Na2SO4, and evaporated to dryness under reduced pressure. The compound was purified by column chromatography on silica (230-400 M) using ethyl acetate/Hexane (40:60) as the eluent to provide the title compound as white solid (0.072 g, 36%). 1H NMR (DMSO-d6, 400 MHz): δ 3.80 (s, 3H), 5.56 (s, 2H), 7.01 (d, J=8.80 Hz, 2H), 7.13 (m, 1H), 7.41-7.50 (m, 4H), 7.90 (br s, 1H), 8.18 (br s, 1H) and 9.18 (s, 1H). MS ES+ (460.32), HPLC (method II) Rt=16.37 min.
