실험 절차

6-(4-Fluoro-2-methoxyphenyl)-5-hydroxymethyl-2,2,4-trimethyl-1,2-dihydroquinoline (Reference Compound No. 4-3, 49.7 mg, 0.15 mmol), 3-aminobenzoic acid (49.0 mg, 0.35 mmol), tri-n-butylphosphine (87.0 μL, 0.35 mmol), and 1,1′-(azodicarbonyl)dipiperidine (89.4 mg, 0.35 mmol) were dissolved in anhydrous benzene (2 mL), and then the mixture was stirred under argon atmosphere at room temperature overnight. Hexane (3 mL)-ethyl acetate (3 mL) were added to the reaction mixture, and unsoluble materials were filtered. The filtrate was concentrated under reduced pressure and the residue was purified by silica gel column chromatography (hexane-ethyl acetate) to give the titled compound (28.0 mg) as a colorless amorphous product. (Yield 42%)
