Conditions

Temperature: 80 °C

Procedure

A mixture of 5-chloromethyl-6-(2-methoxyphenyl)-2,2,4-trimethyl-1,2-dihydroquinoline (Reference Compound 5-1, 52 mg, 0.16 mmol), phenol (42 μL, 0.48 mmol) and potassium carbonate (88 mg, 0.64 mmol) was suspended in anhydrous N,N-dimethylformamide (2 mL), and stirred 80° C. for 5 hours. After cooling down, the reaction mixture was diluted with ethyl acetate (60 mL). The whole was washed with water (50 mL) and saturated brine (30 mL) successively, dried over anhydrous magnesium sulfate, and then the solvent was removed under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane-ethyl acetate) to give the titled compound (24 mg) as a colorless oil. (Yield 39%)
