Reaction Steps
Pd(PPh3)4 (10 mg, 0.009 mmol) was added to a solution of 3-(5-bromofuran-2-yl)-5-fluoro-benzonitrile (180 mg, 86% purity, 0.59 mmol) and 2-trimethylstannylpyridine (193 mg, 0.80 mmol) in toluene (2.5 mL) under argon. The resulting solution was stirred at 110° C. for 48 h. After cooling to room temperature, the solvent was removed in vacuo. Flash chromatography (silica gel, 35-100% dichloromethane in hexane) afforded 67.7 mg (43%) of 3-fluoro-5-(5-(2-pyridyl)-2-furyl)-benzonitrile. 1H-NMR (CDCl3), δ (ppm): 8.64 (d, 1H), 7.76-7.83 (m, 3H), 7.66 (m, 1H), 7.24 (m, 2H), 7.19 (d, 1H), 6.92 (d, 1H).
