실험 절차
To a solution of 2-[2-(4-bromophenyl)ethoxy]ethanol (10.8 g, 0.044 mol; see step (iii) above in DMF (100 mL), CuCN (7.8 g, 0.088 mol) was added and refluxed at 140 to 150° C. overnight. After removal of DMF by distillation, the reaction was quenched by the addition of water. Inorganic matter was removed by filtration and the aqueous layer was extracted with ethyl acetate (4×100 mL). The combined organic layers were washed with water and brine before being concentrated. The crude product was purified by column chromatography (silica gel: 60-120 mesh, petroleum ether:ethyl acetate (75:25) eluent). This yielded 4.3 g (51%) of the sub-title compound.
