Procedure
To a solution of 4-Bromomethyl-2-(4-chloro-phenyl)-5-methyl-oxazole (0.12 g, 0.42 mmol) in 2 ml of anhydrous DMF was added 2,6-Difluoro-3-hydroxy-benzamide (0.072 g, 0.42 mmol) and potassium carbonate (0.203 g, 1.20 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 (50:50) as the eluent to provide the title compound as white solid (0.01 g, 6%). 1H NMR (DMSO-d6, 400 MHz): δ 2.49 (s, 3H), 5.09 (s, 2H), 7.11 (m, 1H), 7.38 (m, 1H), 7.60 (d, J=8.40 Hz, 2H), 7.85 (br s, 1H), 7.95 (d, J=8.40 Hz, 2H) and 8.13 (br s, 1H).
