Reference Example 57 A mixture of 7-bromo-4-fluoro-1-benzofuran (5.30 g), zinc cyanide (1.74 g), tetrakis(triphenylphosphine)palladium(0) (2.85 g), and N,N-dimethylformamide (160 mL) was stirred at 100C for 2.5 hours under argon atmosphere. After cooling to room temperature, the reactant was poured into water and extracted with ethyl acetate. Insolubles were filtered off using celite. The organic layer was washed with brine, dried and concentrated. The obtained residue was purified by silica gel column chromatography to obtain 4-fluoro-1-benzofuran-7-carbonitrile (3.63 g). 1H-NMR (300 MHz, CDCl3) delta: 6.96 (1H, d, J=2.4 Hz), 7.03 (1H, d, J=8.7 Hz), 7.60 (1H, dd, J=8.7 and 5.1 Hz), 7.74 (1H, d, J=2.4 Hz). IR (KBr) 2232, 1497, 1271 cm-1, 253429-31-1
