ステップ1. 2,3,6,7,10,11-ヘキサブロモトリフェニレンの調製
2,3,6,7,10,11-ヘキサブロモトリフェニレンを、文献の方法(Breslowら、Tetrahedron、1982、38、863)に従って調製した。トリフェニレン(3.0g、13.2mmol)を70mLのニトロベンゼンに溶かした。0.27gのFe粉末を加えた。この混合物に、20mLのニトロベンゼン中の臭素(18.6g、120mmol)を滴下漏斗により加えた。混合物を室温で12時間攪拌し、2時間還流させた。冷却後、固体を濾過し、エタノールにより洗い、乾燥した。8.9g(96%)の粗生成物を得た。沸騰1,2-ジクロロベンゼン(約180℃)からの再結晶により、オフホワイトの針状晶として生成物を得た(8.64g、94%)。この生成物は、質量分析によって確認した。
