Reaction Steps

To a solution of 4-Bromomethyl-2-(4-methoxy-phenyl)-5-methyl-oxazole (0.10 g, 0.35 mmol) in 2 ml of anhydrous DMF was added 2,6-Difluoro-3-hydroxy-benzamide (0.061 g, 0.35 mmol) and potassium carbonate (0.171 g, 1.05 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 (0.117 g, 87%). 1H NMR (DMSO-d6, 400 MHz): δ 2.42 (s, 3H), 3.82 (s, 3H), 5.06 (s, 2H), 7.10 (m, 3H), 7.37 (m, 1H), 7.86 (m, 3H) and 8.13 (br s, 1H). MS ES+ (375.12), HPLC (method I) Rt=15.78 min.
