反応混合ポンプ中に連続的に以下の供給流を混合した:
1)組成物:188.9gの1−メチルイミダゾール、249.1gの2,2′,4,4′−テトラメチル−o−ビフェノール及び807.4gのトルエンからなる混合物及び
2)組成物:664.7g(2−t−ブチルフェノキシ)−p−フルオロフェニルクロロホスフィン及び284.9gのトルエンからなる混合物
液流1)を1781ml/時間で、液流2)を1189ml/時間で計量供給した。混合チャンバの容量は3.3mlであった。該システムを2分間、平衡にもたらした。引き続き排出物を平衡化させるために275分にわたって収集した。反応混合ポンプの排出物における反応媒体の温度は69.8℃であった。該排出物は2つの液相からなり、これらを容器中に収集し、引き続き分離した。275分で799.6gの上相及び98.9gの下相を収集した。該上相は反応生成物のトルエン溶液であり、下相は1−メチルイミダゾールの塩酸塩であり、これは75℃より高い温度でイオン性液体として生じる。単離された有用生成物の収量は302.9g(理論値の93.4%)であった。
