실험 절차

1-[1-({3,4-Difluoro-2-[(2-fluoro-4-iodophenyl)amino]phenyl}carbonyl)-3-hydroxyazetidin-3-yl]-2-(1,3-dioxolan-2-yl)ethyl 2,4,6-tris(1-methylethyl)benzenesulfonate (50 mg, 0.060 mmol) was dissolved in tetrahydrofuran (1 mL) and was cooled to 0° C. Sodium hydride (60 wt % dispersion in oil; 7 mg, 0.18 mmol) was added and the mixture was stirred at 0° C. for 45 minutes. The mixture was quenched with saturated sodium bicarbonate solution and partitioned with ethyl acetate. The aqueous portion was extracted with ethyl acetate. The combined organic portion was washed with brine, dried over anhydrous sodium sulfate, filtered and concentrated in vacuo. Column chromatography (silica gel, 50% ethyl acetate in hexanes) gave 6-{[2-(1,3-dioxolan-2-ylmethyl)-1-oxa-5-azaspiro[2.3]hex-5-yl]carbonyl}-2,3-difluoro-N-(2-fluoro-4-iodophenyl)aniline (31 mg, 0.057 mmol, 94% yield): MS (EI) for C21H18F3IN2O4: 547 (MH+).
