Reaction Steps

To a solution of 4-Chloromethyl-2-p-tolyl-oxazole (0.10 g, 0.50 mmol) in 2 ml of anhydrous DMF was added 2,6-Difluoro-3-hydroxy-benzamide (0.08 g, 0.50 mmol) and potassium carbonate (0.233 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 (0.03 g, 18%). 1H NMR (DMSO-d6, 400 MHz): δ 2.37 (s, 3H), 5.13 (s, 2H), 7.11 (m, 1H), 7.36 (d, J=8.0 Hz, 2H), 7.41 (m, 1H), 7.88 (m, 3H), 8.12 (br s, 1H) and 8.29 (s, 1H). MS ES+(345.24), HPLC (method I) Rt=16.07 min.
