Procedure

To 4.6 g of the 4′-(4-bromophenyl)-6-(5H-pyrido[4,3-b]indol-5-yl)-[2,2′;6′,2″]terpyridine obtained in Example 4 were added 1.4 g of 2-naphthaleneboronic acid, 0.5 g of tetrakis(triphenylphosphine)palladium, 21 mL of a 2 M aqueous potassium carbonate solution, 72 mL of toluene, and 18 mL of ethanol, followed by heating with reflux while stirring for 6 hours. After cooling to room temperature, a precipitate was collected by filtration. To the precipitate, 200 mL of o-dichlorobenzene was added and insoluble matter was removed by filtration. The filtrate was concentrated under a reduced pressure to obtain a concentrate. The concentrate was dissolved in chloroform and subjected to adsorptive purification with NH silica gel. Thereafter, the filtrate was concentrated under a reduced pressure to obtain a crude product. The crude product was washed with ethyl acetate to obtain 3.5 g (yield, 69%) of 4′-(4-naphthalen-2-yl-phenyl)-6-(5H-pyrido[4,3-b]indol-5-yl)-[2,2′;6′,2″]terpyridine (Compound 134) as a white powder.
