실험 절차

Into a four-neck flask were weighed 16.89 g (59.0 mmol) of di(1-naphthyl)phosphine, 1.27 g (2.5 mmol) of Pd2(dba)3CHCl3 (dba represents dibenzylideneacetone), and 1.01 g (2.5 mmol) of diphenylphosphinopropane. The atmosphere of the reaction vessel fitted with a thermometer, a condenser tube, and a dropping funnel with a pressure-equalizing tube was completely replaced with nitrogen. Thereto were added 150 mL of toluene, 15.00 g (49.2 mmol) of 2-(trifluoromethanesulfonyl)oxy-bromobenzene (5), and 9.53 g (73.8 mmol) of diisopropylethylamine, followed by 16 hours of heating at reflux. After the completion of the reaction, the reaction mixture was cooled to room temperature and poured into 150 mL of 5% hydrochloric acid aqueous solution. After 30 minutes of stirring, the layers were separated from each other. The organic layer was washed with water and saturated saline and dried over anhydrous magnesium sulfate. Toluene was removed by evaporation and the residue was purified by silica gel column chromatography to obtain the title compound (10.68 g, a pale yellow solid). Yield 49.2%.
