Water → HCID 23013815, compound

In chloroform (12 mL) was dissolved 305 mg (1.86 mmol) of 1-(methoxymethoxy)-2-vinylbenzene obtained in Example 7(2), 5 mL (63 mmol) of 50% aqueous sodium hydroxide solution was added dropwise to the solution, and then, 54.1 mg (0.237 mmol) of benzyl(triethyl)ammonium chloride was added to the same and the resulting mixture was stirred at room temperature overnight. The reaction mixture was poured into water, and extracted with chloroform. The organic layer was successively washed with water and brine, and dried over anhydrous magnesium sulfate. The solvent was distilled off and the obtained residue was purified by preparative thin-layer chromatography (available from MERCK CO., 1.05744, 3 plates were used, developed by ethyl acetate:hexane=1:2) to obtain 387 mg (1.57 mmol, Yield: 84.4%) of 1-(2,2-dichlorocyclopropyl)-2-(methoxymethoxy)benzene.
