To a solution of 2,6-dichloro-nicotinonitrile (3) (7.06 g, 40.8 mmol) in acetonitrile (anhydrous, 300 mL) were added 4-bromo-3-[1,3]dioxolan-2-yl-phenol (2) (10 g, 40.8 mmol) and K2CO3 (5.63 g, 40.8 mmol). The reaction was heated at 65° C. for 3 hours. The solution was filtered and evaporated in vacuo to afford 15.6 g of the product mixture. 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 7.94 (d, J=9.0 Hz, 2 H), 7.62 (d, J=8.6 Hz, 2 H), 7.46 (d, J=3.1 Hz, 1 H), 7.41 (d, J=3.1 Hz, 1 H), 7.18-7.08 (m, 2 H), 7.05 (dd, J=8.8, 2.93 Hz, 1 H), 6.93 (d, J=8.2 Hz, 1 H), 6.11 (s, 1 H), 6.09 (s, 1 H), 4.19-3.99 (m, 8 H).
