10−(ビフェニル−4−イル)−2−フェニル−9,10−ジヒドロアクリジン7.8g(19.0mmol)をクロロホルム300mlに入れ、ブロモスクシンイミド3.7g(21.0mmol)を加えた。反応溶液を常温で2時間攪拌した。反応終了後、反応溶液を蒸留水で洗浄した後、有機層を抽出して硫酸ナトリウムで乾燥し、溶媒を除去した残留物をシリカゲルカラムクロマトグラフィ(塩化メチレン/ノルマルヘキサン=1/10)を行うことで分離精製し、クリーム色の固体状の10−(ビフェニル−4−イル)−2−ブロモ−7−フェニル−9,10−ジヒドロアクリジン化合物6.5g(収率70%)を得た。
4,4’−ビス(ビフェニルアミン)50g(0.182mol)と1−ブロモ−4−ヨードベンゼン62.6g(0.364mol)をトルエン700molに溶解させた。次いで、Pd2(dba)3 5g(5.4mmol)、トリ−tert−ブチルホスフィン2.2g(11mmol)、ナトリウム−tert−ブトキシド21g(0.22mol)をそれぞれ1LのRBFに入れて3時間加熱攪拌した。反応終了後、蒸留水で反応液を洗浄した後、カラムクロマトグラフィを行うことで、白色固体のN−(ビフェニル−4−イル)−N−(4−ブロモフェニル)ビフェニル−4−アミン56g(収率65%)を得た。
