To a solution of 4-Chloromethyl-2-(4-chloro-phenyl)-oxazole (0.20 g, 0.87 mmol) in 2 ml of anhydrous DMF was added 2,6-Difluoro-3-hydroxy-benzamide (0.15 g, 0.78 mmol) and potassium carbonate (0.363 g, 2.60 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 (0.10 g, 31%). 1H NMR (DMSO-d6, 400 MHz): δ 5.14 9s, 2H), 7.12 (t, J=9.20 Hz, 1H), 7.40 (m, 1H), 7.63 (d, J=8.40, 2H), 7.85 (br s, 1H), 8.0 (d, J=8.40 Hz, 2H), 8.13 (br s, 1H) and 8.36 (s, 1H). MS ES+ (365.13), HPLC (method I) Rt=16.36 min.
