Reaction Steps

A mixture of 5-(5-fluoro-2-methylphenoxymethyl)-6-(4-hydroxy-2-methoxyphenyl)-2,2,4-trimethyl-1,2-dihydroquinoline (Reference Compound No. 3-1, 26.0 mg, 0.0600 mmol), 1,1′-carbonyldiimidazole (31.4 mg, 0.194 mmol) and 4-dimethylaminopyridine (1.1 mg, 0.0090 mmol) was dissolved in anhydrous tetrahydrofuran (0.6 mL), and then the mixture was stirred at room temperature for 1 hour. N,N,N′-trimethylethylenediamine (15 μL, 0.12 mmol) was added thereto, the mixture was stirred at room temperature for 1 hour, and then the mixture was purified by silica gel column chromatography (hexane-ethyl acetate) to give the titled compound (10.0 mg) as a colorless amorphous product.
