Reaction Steps

To a stirred solution of rac-4-{[(2R,3S,4R,5S)-3-(3-Chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carbonyl]-amino}-trans-cyclohexylamine trifluoroacetic acid salt (100 mg, 0.126 mmol) in 1,4-dioxane (5 mL), N-trimethylsilyl isocyanate (Aldrich, 42 uL, 0.316 mmol) was added followed by the addition of triethylamine (44 uL, 0.316 mmol). The mixture was stirred at rt overnight. The reaction was quenched with addition of water. The mixture was extracted with methylene chloride (2×10 mL) and the extracts were dried with magnesium sulfate.
