Reaction Steps

A solution of 4′-azido-4,4″-dimethoxy-[1,1′:3′,1″-terphenyl]-5′-carbonitrile (108 mg, 0.303 mmol) in 1,2-dichlorobenzene (2 mL) was heated at 180° C. for 0.5 hr. It was allowed to cool to room temperature and diluted with hexane (about 5 mL). The precipitate was collected by filtration and washed with hexane to leave 7-methoxy-3-(4-methoxyphenyl)-9H-carbazole-1-carbonitrile (72 mg, 72% yield) as an off-white solid. MS (ESI) m/z 329.1 (M+H). 1H NMR (CDCl3) δ ppm 8.51 (1H, s), 8.28 (1H, s), 7.96 (1H, d, J=8.85 Hz), 7.76 (1H, d, J=1.83 Hz), 7.53-7.59 (2H, m), 7.00-7.04 (2H, m), 6.99 (1H, d, J=2.14 Hz), 6.93 (1H, dd, J=8.70, 2.29 Hz), 3.92 (3H, s), 3.87 (3H, s).
