반응 단계

224 mg (2 mmoles) of potassium tert.-butoxide, 70 mg (2.5 mole % calculated for the bromobenzene substrate) of the catalyst of formula (I), 105 μl (1 mmole) of bromobenzene, 198 μl (2 mmoles) of piperidine and 5 ml of solvent were charged into an oven-dried Schlenk tube. The reaction mixture was heated on an oil bath at 110° C. for 24 hours, allowed then to cool to room temperature, and evaporated under reduced pressure. The residue was purified by column chromatography on silica gel (eluant: hexane/ethyl acetate) to give the desired product; 1H NMR (300 MHz, CDCl3) δ 7.31-7.26 (m, 2H), 7.00-6.97 (m, 2H), 6.89-6.84 (m, 1H), 3.19 (t, J=5.6 Hz, 4H), 1.79-1.72 (m, 4H), 1.64-1.59 (m, 2H).
