Procedure

A solution of phenol obtained in step 3 above (1.31 g, 4.8 mmol), 6-chloronicotinonitrile (700 mg, 5.04 mmol) and sodium hydride (290 mg, 7.2 mmol) in DMSO (25 mL) is stirred at room temperature for 18 h. Pour the mixture into iced water and extract the aqueous layer with EtOAc. Dry the organic layer over Na2SO4, filtrate and eliminate the solvent. Purify by flash chromatography (EtOAc/hexane 20/80 and 34/66) to get the title compound (950 mg, 51%). 1H-NMR (CDCl3, 200 MHz): 8.41 (dd, 1H, J=0.8 and 2.1 Hz), 7.97 (dd, 1H, J=2.4 and 8.6 Hz), 7.18 (dd, 1H, J=0.8 and 8.6 Hz), 6.92-6.81 (m, 2H), 3.39 (q, 2H, J=6.9 Hz), 2.81 (t, 2H, J=6.7 Hz), 1.45 (s, 9H).
