実験手順

Chlorodiphenylmethane (0.50 g, 2.47 mmol) (Wako Pure Chemical Industries, Ltd.), pyrrolidine (0.53 g, 7.45 mmol) (Tokyo Chemical Industry Co., Ltd.), and potassium iodide (0.10 g, 0.60 mmol) (Wako Pure Chemical Industries, Ltd.) were added to acetonitrile (20 mL) (Wako Pure Chemical Industries, Ltd.), and the mixture was refluxed for 2 hours. The mixture was allowed to cool to room temperature. After that, a saturated aqueous solution of sodium hydrogen carbonate (Wako Pure Chemical Industries, Ltd.) was added to the reaction solution, and mixture was extracted with ethyl acetate (Wako Pure Chemical Industries, Ltd.). The organic layer was dried with anhydrous sodium sulfate (Wako Pure Chemical Industries, Ltd.), and the solvent was distilled off under reduced pressure. The residue was subjected to silica gel column chromatography (chloroform (Wako Pure Chemical Industries, Ltd.):methanol (Wako Pure Chemical Industries, Ltd.)=99:1 as an eluent), to thereby obtain the title compound (0.36 g, 61% yield).
