Procedure
The title compound was prepared (2.71 g, 76%) using a similar procedure t as set out earlier in Description 7 using crude 1-(1,1-dimethylethyl) 2-methyl (2S,5R)-5-{4-[(phenylmethyl)oxy]phenyl}-1,2-pyrrolidinedicarboxylate (D6, 3.25 g, 7.89 mmol) and bromoacetonitrile (3.3 ml, 47.38 mmol in 40 ml THF); Rt (HPLC): 6.4 min; Rf (cyclohexane:ethyl acetate=7:3): 0.40; MS: (ES/+) m/z: 473 [M+Na+]; C26H30N2O5 requires 450; 1H NMR (500 MHz, DMSO-d6) δ(ppm): 7.46-7.24 (m, 7H); 6.94 (d, 2H); 5.11 (s, 2H); 4.94-4.78 (m, 1H); 3.78 (s, 3H); 3.33 (d, 1H); 3.22 (d, 1H); 2.66-2.52 (m, 1H); 2.42-2.29 (m, 1H); 2.29-2.16 (m, 1H); 1.92-1.77 (m, 1H); 1.38-0.97 (br. s, 9H); NOE between the aromatic protons and the methyl ester could be observed.
