[OH:1][C:2]1[CH:7]=[CH:6][CH:5]=[CH:4][C:3]=1[C:8](=[O:10])[CH3:9].[CH3:11][O:12][CH2:13]Cl.C(=O)([O-])[O-].[K+].[K+]>CN(C)C=O>[CH3:11][O:12][CH2:13][O:1][C:2]1[CH:7]=[CH:6][CH:5]=[CH:4][C:3]=1[C:8](=[O:10])[CH3:9]A 10 g quantity of 1-(2-hydroxyphenyl)ethanone was dissolved in 100 ml of dimethylformamide, and 11.2 ml of chloromethyl methyl ether and 25.4 g of potassium carbonate were added. The mixture was stirred at 50° C. for 6 hours and then at room temperature for 4 days. After insolubles were removed from the reaction mixture by filtration, ice water was added to the filtrate and extraction with ethyl acetate was performed. The organic layer was washed with water and dried over anhydrous magnesium sulfate. The organic layer was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=5:1) to give 6.26 g of colorless oily 1-(2-methoxymethoxyphenyl)ethanone.
