まず、2,3−ジフェニル−5−クロロピラジン1.02g、3−シアノフェニルボロン酸0.62g、テトラキストリフェニルホスフィンパラジウム(0)(略称:Pd(PPh3)4)0.15g、トルエン10mL、エタノール1.5mL、炭酸カリウム1.16g、水4.2mLを、還流管をつけたナスフラスコに入れ、フラスコ内をアルゴン置換した。その後、マイクロ波(2.45GHz 100〜150W)を45分間照射し、反応させた。この混合物に水を加え、ジクロロメタンを抽出溶媒として有機層を抽出した。得られた有機層を無水硫酸マグネシウムにて乾燥した。乾燥した後の溶液をろ過した。この溶液の溶媒を留去した後、留去により得られた残渣を、ジクロロメタンと酢酸エチルの混合液を展開溶媒とするシリカゲルカラムクロマトグラフィーで精製することにより、白色粉末状固体を収率42%で得た。なお、マイクロ波の照射はマイクロ波合成装置(CEM社製 Discover)を用いた。ステップ1の合成スキームを下記(a−1)に示す。
ステップ1に続いて、2−エトキシエタノール6mL、水2mL、上記ステップ1で得たピラジン誘導体Hdppr−3CP0.52g、塩化イリジウム水和物(IrCl3・H2O)(Sigma−Aldrich社製)0.22gを、還流管を付けたナスフラスコに入れ、フラスコ内をアルゴン置換した。その後、マイクロ波(2.45GHz 100W)を30分間照射し、反応させた。反応溶液より析出してきた橙色粉末をろ過し、エタノールにて洗浄することにより、複核錯体[Ir(dppr−3CP)2Cl]2を得た(収率70%)。ステップ2の合成スキームを下記(b−1)に示す。
ステップ2に続き、2−エトキシエタノール10mL、上記ステップ2で得た複核錯体[Ir(dppr−3CP)2Cl]2 0.46g、アセチルアセトン0.081mL、炭酸ナトリウム0.28gを、還流管を付けたナスフラスコに入れ、フラスコ内をアルゴン置換した。その後、マイクロ波(2.45GHz 100W)を20分間照射し、反応させた。反応溶液をろ過し、得られたろ液の溶媒を留去した。留去により得られた残渣を、メタノールにて再結晶することにより、赤色粉末状固体を、収率6%で得た。ステップ3の合成スキームを下記(c−1)に示す。
