Reaction Steps

To a solution of 4-Chloromethyl-2-(4-methoxy-phenyl)-oxazole (0.100 g, 0.4 mmol) in 2 ml of anhydrous DMF was added 2,6-Difluoro-3-hydroxy-benzamide (0.077 g, 0.40 mmol) and potassium carbonate (0.216 g, 1.50 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 (0.044 g, 27%). 1H NMR (DMSO-d6, 400 MHz): δ 4.01 (s, 3H), 5.12 (s, 2H), 7.10 (m, 3H), 7.40 (m, 1H), 7.85 (br s, 1H), 7.93 (d, J=8.80 Hz, 2H), 8.13 (br s, 1H) and 8.25 (s, 1H). MS ES+(361.16), HPLC (method I) Rt=15.47 min.
