实验过程

NaH (60% in mineral oil, 60 mg, 1.50 mmol) was added an ice-cooled solution of 2-iodo-4-(1-phenyl-cyclohexyl)-phenol (400 mg, 1.06 mmol) in DMF (10 mL). Methyl iodide (125 μL, 2.0 mmol) was added. The reaction temperature was allowed to reach room temperature. The mixture was stirred for 2 h, then quenched with water 10 mL and extracted with dichloromethane (2×20 mL). The combined organic phase was dried (Na2SO4) and concentrated in vacuo. The residue was taken up in water (20 mL) and extracted with dichloromethane. The organic phase was dried (Na2SO4) and concentrated in vacuo. 1H-nmr of the syrup (430 mg) indicated full conversion to the methyl ether. 1H NMR (400 MHz, CDCl3): 7.71 (d, 1H, J=2.1 Hz), 7.32-7.25 (m, 4H), 7.18 (dd, 1H, J=2.1 Hz, J=8.8 Hz), 7.17-7.13 (m, 1H), 6.72 (d, 1H, J=8.8 Hz), 3.83 (s, 3H), 2.32-2.18 (m, 4H), 1.62-1.44 (m, 6H).
