실험 절차

1,4-Dioxane (10 ml) and 3 M aq K3PO4 (1.12 mL, 3.3 mmol) was added to a flask containing [4-(methylthio)phenyl]boronic acid (0.283 g, 1.68 mmol), Pd(dppf)Cl2 (82 mg, 0.112 mmol) and ethyl (2R)-4-(5-fluoro-4-iodo-2-oxopyridin-1(2H)-yl)-2-methyl-2-(methylsulfonyl)butanoate, T2, (500 mg, 1.12 mmol) that was previously flushed with nitrogen. The mixture was heated to 60° C. and stirred at this temperature for 1 h. The reaction mixture was diluted with EtOAc and washed with water. The organics were dried (MgSO4), filtered, and concentrated. The crude product was purified via flash chromatography on a 40 g silica column and an eluent of EtOAc in n-heptane (0-100%) to afford the title compound as a gum (492 mg, 99%). MS (LCMS) m/z 442.1 (M+1). 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 1.17-1.27 (m, 3H) 1.74 (s, 3H) 2.38-2.61 (m, 5H) 3.09 (s, 3H) 3.88-4.02 (m, 1H) 4.17-4.32 (m, 3H) 6.57 (d, J=7.61 Hz, 1H) 7.21-7.34 (m, 3H) 7.37-7.48 (m, 2H).
