Reaction Steps

To a solution of 4-(5-Bromo-2-bromomethyl-thiazol-4-yl)-benzonitrile (0.43 g, 1.20 mmol) in 5 ml of anhydrous DMF was added 2,6-difluoro-3-hydroxy-benzamide (0.20 g, 1.20 mmol) and potassium carbonate (0.58 g, 4.20 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 as a white solid (0.35 g, 66%). 1H NMR (DMSO-d6, 400 MHz): δ 5.57 (s, 2H), 7.13 (m, 1H), 7.44 (m, 1H), 7.89 (br s, 1H), 8.0 (d, J=8.40 Hz, 2H), 8.10 (d, J=8.40 Hz, 2H) and 8.17 (br s, 1H). MS ES+ (450.09), HPLC (method I) Rt=16.127 min.
