Sodium Iodide → 1-(Cyclopropylmethoxy)-3-ethynylbenzene

Participants

Reaction Steps

To a solution of 3-ethynylphenol (1.18 g, 10.0 mmol) in acetone (30 mL) is added (bromomethyl)cyclopropane (1.02 mL, 10.0 mmol), sodium iodide (0.75 g, 5.0 mmol) and Cs2CO3 (6.52 g, 20.0 mmol) at room temperature. After refluxing over night, the reaction mixture is cooled, diluted with Et2O (300 mL) and pass through a thin layer of silica gel. The solution is concentrated. The crude material is purified by chromatography (silica gel, EtOAc/hexane: 1/99) to give the title compound (1.45 g, 84%) as an oil. MS(+) APPI: 173 (M+H)+.
