Pyridine → 3-{4-[3-(4-Nitrophenyl)-2-oxo-2H-pyridin-1-yl]phenyl}propionic acid ethyl ester

Participants

Reaction Steps

3-(4-Nitrophenyl)-1H-pyridin-2-one (P3) (0.2 g, 0.92 mmol), copper (II) acetate (0.334 g, 2 equiv.), diisopropylethylamine (0.31 mL, 2 equiv.), and pyridine (0.15 mL, 2 equiv.) were added to a stirred solution of 4-(2-ethoxycarbonylethyl)phenyl boronic acid (0.308 g, 1.3 mmol) in dichloromethane (10 mL). The reaction mixture was then stirred under argon at room temperature for 4 hours. The solution was then filtered through celite, concentrated and purified by chromatography on silica gel (50% v/v ethyl acetate in hexane) to afford the title compound as an oil.
