실험 절차

5-Hydroxymethyl-6-(2-methoxy-4-methoxymethoxyphenyl)-2,2,4-trimethyl-1,2-dihydroquinoline (Reference Compound No. 1, 1.00 g, 2.71 mmol), 2-methylbenzoic acid (739 mg, 5.43 mmol), tri-n-butylphosphine (1.35 mL, 5.40 mmol), and 1,1′-(azodicarbonyl)dipiperidine (1.37 g, 5.43 mmol) were dissolved in anhydrous benzene (30 mL), and then the mixture was stirred under argon atmosphere at room temperature overnight. Hexane (30 mL) was added to the reaction mixture, and then the unsoluble materials were filtered out. The filtrate was concentrated under reduced pressure, and then the residue was purified by silica gel column chromatography (hexane-ethyl acetate) to give the titled reference compound (967 mg) as a colorless amorphous product. (Yield 73%)
