Procedure

5-(5-Fluoro-2-methylphenoxymethyl)-6-(4-hydroxy-2-methoxyphenyl)-2,2,4-tri methyl-1,2-dihydroquinoline (Reference Compound No. 5-3, 20.1 mg, 0.046 mmol), potassium carbonate (16.7 mg, 0.12 mmol) and benzyl bromide (6.6 μL, 0.055 mmol) were dissolved in anhydrous N,N-dimethylformamide (0.5 mL), and the mixture was stirred at 60° C. for 40 minutes. Ethyl acetate (50 mL) was added to the reaction mixture, and the whole was washed with water (50 mL) and saturated brine (30 mL), dried over anhydrous magnesium sulfate, and then the solvent was removed under reduced pressure. The residue was purified by silica gel column chromatography (hexane-ethyl acetate) to give the titled compound (5.1 mg) as a colorless oil. (Yield 19%)
