Versuchsvorschrift

In a manner similar to the method described in Examples 117d and 117e, rac-(2R,3S,4R,5S)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-5-{2,2-dimethyl-4-[2-(2,2,2-trifluoro-acetoxy)-ethoxy]-butyl}-pyrrolidine-2-carboxylic acid trifluoroacetic acid prepared in Example 119c (0.37 g, 0.58 mmol) was reacted with 2-((S)-2,2-dimethyl-[1,3]dioxolan-4-yl)-ethylamine (0.25 g, 1.7 mmol), HATU (0.4 g, 1 mmol) and iPr2NEt (0.5 mL, 2.9 mmol) in CH2Cl2 at room temperature for 20 h, then treated with aqueous saturated K2CO3 solution in tetrahydrofuran, followed by reaction with aqueous HCl solution in tetrahydrofuran at room temperature to give rac-(2R,3S,4R,5S)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-5-[4-(2-hydroxy-ethoxy)-2,2-dimethyl-butyl]-pyrrolidine-2-carboxylic acid ((S)-3,4-dihydroxy-butyl)-amide as a light yellow solid (90 mg, 25%).
