Reaction Steps

2-[3,5-Bis(methoxymethoxy)-2-phenylphenyl]ethanol (1.2 g, 3.7 mmol) obtained in Example 3, Step 3 was dissolved in N,N-dimethylformamide (15 mL), and a 60% sodium hydride dispersion in mineral oil (0.30 g, 7.5 mmol) was added thereto in an atmosphere of nitrogen, followed by stirring at 4° C. for 4 minutes. After methyl iodide (0.70 mL, 11 mmol) was added dropwise to the reaction mixture, the mixture was stirred at 4° C. for 1 hour, followed by further stifling for 48 hours, while the temperature of the mixture was raised to room temperature. To the reaction mixture was added water (10 mL) and a saturated aqueous solution of ammonium chloride (20 mL), and the mixture was extracted with ethyl acetate (0.10 L). The organic layer was washed with water (0.10 L) and dried over anhydrous sodium sulfate, followed by concentration under reduced pressure. The resulting residue was purified by silica gel column chromatography (ethyl acetate/hexane=1/9-1/2) to obtain 3,5-bis(methoxymethoxy)-1-(2-methoxyethyl)-2-phenylbenzene (1.1 g, 91%).
