실험 절차

To a solution of chiral 2-iodoethyl 4-((2R,3S,4R,5S)-3-(3-chloro-2-fluorophenyl)-4-(4-chloro-2-fluorophenyl)-4-cyano-5-neopentylpyrrolidine-2-carboxamido)-3-methoxybenzoate (Example 11, 20 mg, 0.026 mmol) in dimethyl formamide (2 mL) was added potassium di-tert-butylphosphate (Accela ChemBio, 21.8 mg, 0.088 mmol). The reaction mixture was heated at 60° C. for 6 h. The mixture was diluted with ethyl acetate, washed with water and then brine, dried over anhydrous sodium sulfate and concentrated. The crude material was purified by flash chromatography to give chiral 2-(di-tert-butoxyphosphoryloxy)ethyl 4-((2R,3S,4R,5S)-3-(3-chloro-2-fluorophenyl)-4-(4-chloro-2-fluorophenyl)-4-cyano-5-neopentylpyrrolidine-2-carboxamido)-3-methoxybenzoate (12 mg, 54% yield). MS (ES+) m/z calcd. for C41H50Cl2F2N3O8PNa: [(M+Na)+]: 874. found: 874.
