실험 절차

To a solution of 2-(2,4-difluorophenoxy)-2-methylpropanoic acid (10.0 g, 46.3 mmol, Chembridge) in methylene chloride (200 mL) were added 1-hydroxybenzotriaole hydrate (8.5 g, 55.5 mmol, Aldrich), N-(3-dimethylaminopropyl)-N-ethylcarbodimide hydrochloride (10.6 g, 55.5 mmol, Aldrich) and ammonium hydroxide (54.0 g, 463 mmol). The reaction mixture was stirred at room temperature for 16 hours and then quenched with water (100 mL). The aqueous layer was extracted with methylene chloride (3×100 mL). The combined organic extracts were washed with brine, 5% citric acid, and brine (100 mL each), dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure to obtain the titled compound. MS (ESI+) m/z 233 (M+NH4)+.
