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 (431.4 mg, 1.00 mmol) prepared in Example 1d, 2-((S)-2,2-dimethyl-[1,3]dioxolan-4-yl)-ethylamine (217.5 mg, 1.5 mmol), HATU (570.30 mg, 1.50 mmol) and iPr2NEt (258.6 mg, 2.00 mmol) in CH2Cl2 (20 mL) was stirred at rt for 1 hour. 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 the residue was treated with PPTS (cat) in MeOH (20 mL) at 120° C. for 5 min with CEM microwave reactor. The reaction mixture was concentrated and the residue was diluted with EtOAc and washed with water, brine. The organic phase was separated, filtered and dried over Na2SO4. The mixture was then concentrated and purified by SiO2 flash column (5% of MeOH in EtOAc) 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 ((S)-3,4-dihydroxy-butyl)-amide (450.0 mg, 86.7%) as a white amorphous.
