To a solution of cyclohexanol (0.76 g, 7.56 mmol) in anhydrous THF (10 mL), NaH (60%, 0.18 g, 7.56 mmol) was added in portions at 0° C. The mixture was stirred at 0° C. for 0.5 h, and then 2-(4-(5-bromo-2-chlorobenzyl)phenoxy)ethyl 4-methylbenzenesulfonate (intermediate AB) (0.66 g, 1.26 mmol) was added in portions. Then the mixture was stirred at room temperature overnight, whereupon TLC showed the reaction was complete. Then the reaction mixture was quenched with saturated NH4Cl, extracted with EtOAc, washed with water and brine, dried with anhydrous Na2SO4, and concentrated to a crude oil. The crude oil was purified by column chromatography (PE:EA=100:1) to obtain oil AE (0.3 g, yield 56.6%). 1H NMR (400 MHz, CD3OD): δ 7.28-7.21 (m, 3H), 7.07 (d, 2H, J=8.8 Hz), 6.86 (d, 2H, J=8.4 Hz), 4.08 (t, 2H, J=4.8 Hz), 3.98 (s, 2H), 3.80 (t, 2H, J=4.8 Hz), 3.40-3.20 (m, 1H), 1.95-1.93 (m, 2H), 1.76-1.73 (m, 2H), 1.32-1.22 (m, 6H).
