Reaction Steps

The mixture of the 2-bromo-1-[4-(methylsulfonyl)phenyl]ethanone (500 mg, 1.8 mmol) and pyridine 2-carboxamide (551 mg, 4.51 mmol) was heated to 150° C. for 1 hour. Then the reaction mixture was cooled, and partitioned between ethyl acetate and water. The aqueous layer was extracted with ethyl acetate twice, and the combined organic layers were washed with water and brine, dried over MgSO4. After concentration, the solid residue was dissolved in methanol and subject to mass-directed HPLC purification to give 21 mg of 2-{4-[4-(methylsulfonyl)phenyl]-1,3-oxazol-2-yl}pyridine. LCMS: m/z 301.0 (M+H)+.
