To a stirred solution of (4-hydroxy-phenyl)-pyridin-2-yl-methanone (2.5 g, 0.0125 mol) in DMF (35 mL) was added cesium carbonate (6.14 g, 0.0188 mol). The resulting mixture was stirred for 15 minutes before addition of 2,3-dichloro pyrazine(1.87 g, 0.0125 mol) at 0° C. The reaction mixture was heated to 80° C. for 16 h. The reaction mixture was partitioned between water (100 mL) and ethyl acetate (2×100 mL). The organic layer was dried over sodium sulphate and concentrated to afford the product. MS (ESI, pos. ion) m/z: 312 (M+1). IC50 (uM) 30.
