実験手順

Methyl 2-(2-(4-iodophenyl)acetamido)-4-methylthiophene-3-carboxylate (420.4 mg, 1.01 mmol), 4-pyridylboronic acid (Aldrich, 167 mg, 1.36 mmol), tetrakis(triphenylphosphine)palladium(0) (123 mg, 0.11 mmol), and potassium carbonate (565 mg, 4.1 mmol) were combined in DME (2 mL) and water (1 mL) in a sealed tube, and heated to 80° C. over 17 h. The reaction mixture was cooled to rt, then partitioned between EtOAc and water. The organic layer was separated, washed (brine), dried (Na2SO4), filtered and concentrated under reduced pressure. Flash chromatography (EtOAc/hexanes) afforded the titled compound. 1H NMR (CDCl3) δ11.3 (s, 1H), 8.67 (dd, J=4.7, 1.4H, 2H), 7.67 (d, J=8.2 Hz, 2H), 7.60-7.40 (m, 4H), 6.38 (s, 1H), 3.88 (s, 2H), 3.80 (s, 3H), 2.33 (s, 3H); 13C NMR (CDCl3) δ167.7, 166.6, 150.3, 149.9, 147.8, 137.4, 134.8, 134.6, 130.3, 127.7, 121.5, 113.0, 112.3, 51.5, 43.5, 17.8; MH+ 367.1.
