Procedure

118 mg of zinc cyanide, 69.3 mg of Pd(PPh3)4 and 3 mL of DMF were added to 511 mg of the bromo compound obtained in Example 9, and heated under a nitrogen atmosphere at 80° C., and the reaction mixture was stirred for 39 hours. After cooled, the reaction mixture was diluted with 30 mL of ethyl acetate, washed successively with diluted aqueous ammonia, water and saturated brine, then dried over sodium sulfate, and concentrated. Ethyl ether was added to the resulting residue, and the insoluble solid thus formed was taken out through filtration. This was washed with ethyl ether and dried under reduced pressure to obtain the intended compound as a pale yellow-brown solid. 1H-NMR (300 MHz, CDCl3) δ: 8.20 (1H, d, J=2.0 Hz), 7.71 (1H, d, J=8.2 Hz), 7.74 (1H, dd, J=8.6, 2.0 Hz), 7.42 (1H, t, J=8.2 Hz), 7.19 (1H, s), 7.13 (1H, d, J=8.6 Hz), 7.08 (1H, d, J=8.2 Hz), 4.63-4.54 (1H, m), 4.26-4.17 (1H, m), 4.08 (3H, s), 4.03 (3H, s), 3.64-3.52 (1H, m), 3.42-3.29 (1H, m), 2.88 (1H, d, J=16.8 Hz), 2.81 (1H, d, J=16.8 Hz), 2.23-2.13 (1H, m), 2.09-1.85 (3H, m).
