実験手順
A mixture of (4-nitro-phenyl)-acetic acid methyl ester (3.0 g, 15 mmol), 18-crown-6 (396 mg, 1.5 mmol), and methyl iodide (3.74 mL, 60 mmol) were combined in DMF (50 mL) and cooled to 0° C. Sodium hydride (660 mg, 16.5 mmol) was added. The solution was stirred with warming to room temperature overnight. The solution was partitioned between ethyl acetate and water. The combined organic layers were washed with brine, dried (MgSO4), filtered, and concentrated under vacuum to provide 2.19 g (70%) of the title compound. MS (DCI) m/e 210 (M+H)+.
