Procedure

5-Hydroxymethyl-6-(2-methoxy-4-methoxymethoxyphenyl)-2,2,4-trimethyl-1,2-dihydroquinoline (Reference Compound No. 1-1, 511.7 mg, 1.39 mmol), 5-fluoro-2-methylphenol (182 μL, 1.67 mmol), tri-n-butylphosphine (521 μL, 2.09 mmol), and 1,1′-(azodicarbonyl) dipiperidine (526 mg, 2.08 mmol) were dissolved in anhydrous benzene (8 mL), and then the mixture was stirred under argon atmosphere at room temperature for 1 hour. Hexane (15 mL) was added to the reaction mixture, and the 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 reference compound (411.4 mg) as a colorless amorphous product. (Yield 62%)
