Reaction Steps
2-Chloro-4-iodopyridine (1.6 mmol), 4-cyanophenyl boronic acid (2.5 mmol), 2 M potassium carbonate (3.3 mmol), tetrakis(triphenyphosphine)palladium(0) (0.01 mmol) and dioxane (8 mL) were combined in a vial and heated by microwave for 10 min at 150° C. The crystallized product was filtered and subsequently dried in vacuo to yield 250 mg of 4-(2-chloropyridin-4-yl)-benzonitrile as yellow needles. 1H NMR (400 MHz, CDCl3) δ 8.52 (d, J=5.1 Hz, 1H), 7.81 (d, J=8.4 Hz, 2H), 7.72 (d, J=8.2 Hz, 2H), 7.55 (m, 1H), 7.43 (dd, J=5.2, 1.4 Hz, 1H); EIMS 214 m/z (M+).
