실험 절차

To a solution of di-tert-butyl (2S,2′S)-2,2′-{[(1S,4S)-1,4-dihydroxybutane-1,4-diyl]bis(6-fluoro-1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-benzimidazole-5,2-diyl)}dipyrrolidine-1-carboxylate (100 mg, 0.10 mmol) in CH2Cl2 (1 mL) at −20° C. was added triethylamine (0.044 mL, 0.31 mmol) followed by mesyl chloride (0.018 mL, 0.23 mmol) and the solution stirred at −20° C. for 1 hour. 4-tert-Butyl aniline (0.083 mL, 0.52 mmol) was added in one portion, and the solution was allowed to warm to room temperature overnight, with stirring. The solution was diluted with EtOAc, washed with 1N HCl, H2O, and brine, dried (Na2SO4), filtered and concentrated. Purification by flash chromatography (0-50% EtOAc/hexane) gave the title compound (46 mg, 0.04 mmol, 41%).
