6-(4-Hydroxy-2-methoxyphenyl)-5-(2-methoxyphenylaminomethyl)-2,2,4-trimethyl-1,2-dihydroquinoline (Reference Compound No. 4-1, 25.0 mg, 0.0581 mmol) was dissolved in methylene dichloride (0.5 mL), and then triethylamine (16.2 μL, 0.116 mmol) and benzoyl chloride (8.7 μL, 0.075 mmol) were added thereto successively under ice cooling. The reaction mixture was stirred under ice cooling for 30 minutes. The reaction mixture was purified by silica gel column chromatography (hexane-ethyl acetate) to give the titled compound (13.0 mg) as a colorless amorphous product. (Yield 65%)
