Reaction Steps

5-(5-Fluoro-2-methylphenoxymethyl)-6-(5-hydroxy-2-methoxyphenyl)-2,2,4-trimethyl-1,2-dihydroquinoline (Reference Compound No. 5-2, 62.5 mg, 0.14 mmol) and triethylamine (154 μL, 1.11 mmol) were dissolved in anhydrous methylene dichloride (1 mL), acetic anhydride (52 μL, 0.55 mmol) was added thereto, and then the mixture was stirred at room temperature for 1.5 hours. Chloroform (10 mL) was added to the reaction mixture, the mixture was washed with water (10 mL) and saturated brine (300 mL) successively, 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 (56.6 mg) as a colorless amorphous product. (Yield 83%)
