実験手順

A solution of mesylate 105 (26.38 g, 63.57 mmol) in anhydrous N,N-dimethylformamide (DMF, 120 mL) was treated with solid potassium phthalimide (12.95 g, 70.0 mmol, 1.1 equiv) at 25° C., and the resulting reaction mixture was warmed to 70° C. for 2 h. When TLC and HPLC showed the reaction was complete, the reaction mixture was cooled to room temperature before being quenched with H2O (400 mL). The resulting mixture was stirred at room temperature for 10 min before being cooled to 0-5° C. for 1 h. The white precipitate was collected by filtration, washed with water (3×100 mL), and dried in vacuo to afford the desired (5R)-2-[3-(3-fluoro-4-iodo-phenyl)-2-oxo-oxazolidin-5-ylmethyl]-isoindole-1,3-dione 106 (27.85 g, 94%) as an off-white powder. This product was directly used in subsequent reactions without further purification. C18H12FIN2O4, LCMS (EI) m/e 467 (M++H).
