실험 절차

A solution of 1-(2-chloroethoxy)-4-(benzyl)benzene (734 mg, 2.97 mmol) and sodium iodide (1.78 g, 11.9 mmol) in 2-butanone (30 mL) was heated at reflux for 16 hours. After cooling, water was added. The mixture was extracted with ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate, and concentrated under reduced pressure. Flash chromatography gave 732 mg of 1-(2-iodoethoxy)-4-(benzyl)benzene, 1H NMR (300 MHz, CDCl3) δ 7.29 (dd, 2H), 7.19 (dd, 1H), 7.18 (d, 2H), 7.11 (d, 2H), 6.84 (d, 2H), 4.23 (t, 2H), 3.94 (s, 2H), 3.41 (t, 2H) ppm.
