反応手順
25 g of 3,4,5-trimethoxyphenol was dissolved in 100 ml of DMF, and 7.1 g of sodium hydride, (55% oil suspension) was added thereto and cooled by ice while stirring. Then, 12.4 ml of methoxymethyl chloride was added thereto with ice cooling, and the mixture was stirred at room temperature for 30 min. The reaction mixture was poured into ice water and extracted with ethyl acetate. The organic phase was washed with water and dried over anhydrous magnesium sulfate, and the solvent was distilled off. The residue was purified by silica gel column chromatography (eluent; n-hexane : ethyl acetate=85 : 15) to prepare 30.4 g of the product compound as a colorless oleaginous substance.
