A mixture of 2-bromo-4-(methylsulfonylmethyl)-1-(2,2,2-trifluoroethoxyl)benzene (100 mg, 0.29 mmol), 6-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)furo[2,3-c]pyridin-7-one (96 mg, 0.35 mmol), K3PO4 (184 mg, 0.87 mmol), Pd(dppf)Cl2 (22 mg, 10%) in dioxane/H2O (2 mL/1 mL) was bubbled with nitrogen for 5 min. The sealed vial was heated to 70° C. for 2 h. The reaction mixture was filtered through a short plug of celite; the celite plug was washed with EtOAc (15 mL). The filtrate was washed with water and brine; the organic layer was dried over sodium sulfate, filtered and concentrated in vacuo. The resulting residue was purified by prep-HPLC to afford the title compound (40 mg, 33%) as an off-white solid. 1H NMR (CDCl3, 400 MHz) δ 7.76 (d, J=2.0 Hz, 1H) 7.53 (d, J=2.0 Hz, 1H) 7.41-7.38 (m, 1H) 7.37 (s, 1H) 7.02 (d, J=8.4, 1 H) 6.72 (d, J=2.0 Hz, 2H) 4.37 (q, J=8.0 Hz, 2H) 4.27 (s, 2H) 3.73 (s, 3H) 2.89 (s, 3H).
