实验步骤: A mixture of rac-(2R,3R,4R,5S)-3-(3-chloro-phenyl)-4-(4-chloro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carboxylic acid (86.2 mg, 0.20 mmol), 2,2′-oxybis(ethylamine) (31.3 mg, 0.3 mmol), 2-(7-azabenzotriazol-1-yl)-n,n,n′,n′-tetramethyluronium hexafluorophosphate (HATU, 76 mg, 0.2 mmol) and iPr2NEt (0.1 mL, 0.55 mmol) in CH2Cl2 (2 mL) was stirred at rt overnight. The mixture was then diluted with CH2Cl2 and washed with water, brine. The organic phase was separated, filtered and dried over Na2SO4. The mixture was then concentrated and purified by reverse phase chromatography (20-95% of ACN/water) to give rac-(2R,3R,4R,5S)-3-(3-chloro-phenyl)-4-(4-chloro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carboxylic acid [2-(2-amino-ethoxy)-ethyl]-amide (20.3 mg, 19.6%) as an off-white powder.

实验步骤: The aminoethyl ether of Example 1 as the acetate (210 mg, 0.180 mmol) was dissolved in N,N-dimethylformamide (2 mL). To this solution 1M sodium bicarbonate (200 μL, 0.200 mmol) and pentafluorophenyl N-benzyloxycarbonylglycinate (106 mg, 0.270 mmol) were added. After 1 h, the reaction mixture was diluted with water (2×). Isolation by reverse-phase (C18) flash column chromatography eluting with 50-80% acetonitrile/water gave, after lyophilization of the product-containing fractions, the N-CBZ glycine conjugate of the above formula was obtained (130 mg): Isolation by reverse-phase (C18) flash column chromatography eluting with 50-80% acetonitrile/water gave
