実験手順
To a flask, 2-fluoro-5-methoxyphenol (6.00 g, 42 mmol), triethylamine (5.77 g, 57 mmol), and tetrahydrofuran (36.0 mL) were added, and the resulting mixture was cooled in an ice water bath under nitrogen atmosphere. To the solution, a solution of tert-butyldimethylsilyl chloride (6.89 g, 44 mmol) in tetrahydrofuran (30.0 mL) was added dropwise, and the resulting mixture was stirred overnight at room temperature. To the reaction mixture, heptane and a 2 N aqueous sodium hydroxide solution were added, and the resulting mixture was extracted. The organic layer was washed with water, and concentrated under reduced pressure to obtain the captioned compound (10.2 g) as a light brownish-red oil.
