To the solution of (2-bromophenyl)acetonitrile (1.05 g, 5.38 mmol) in THF (20 mL) at 0° C. was added L DS (5.9 mL, 1.0 M). The mixture was stirred at 0° C. for 30 min followed by the addition of a solution of 3-[chloro(pyridin-3-yl)methyl]pyridine (1.1 g, 5.38 mmol) in THF (5 mL). The mixture was stirred at 0° C. for 2 h and the reaction was quenched with water (20 mL) and extracted with CH2Cl2. The combined organic layer was dried, filtered, and concentrated to give a solid. The solid was purified by silica gel chromatography (3% MeOH in CH2Cl2) to give 2-(2-bromophenyl)-3,3-dipyridin-3-ylpropanenitrile. 1H-NMR (500 MHz, CDCl3) δ 8.57-8.54 (m, 3H), 8.26 (d, 1H, J=2.0, 2.0), 7.76 (d, 1H, J=7.8), 7.73 (d, 1H, J=8.1), 7.59 (d, 1H, J=7.8), 7.34-7.11 (m, 5H), 5.12 (d, 1H, J=6.1), 4.58 (d, 1H, J=6.1). LRMS m/z (M+H) Calcd: 364.3, found: 363.9.
