Procedure

To a stirred solution of methyl 4-[5-(R)-phenyl-2-(S)-pirrolidinylmethoxy]benzoate (142 mg, 0.46 mmol), 4-[N′-(2-chlorophenyl)ureido]-3-methoxyphenylacetic acid (153 mg, 0.46 mmol) and N,N-dimethylaminopyridine (55.7 mg, 0.46 mmol) in DMF (10 ml) was added EDC.HCl (95.7 mg, 0.50 mmol) at it, and the resulting mixture was stirred overnight. The reaction mixture was poured into water and extracted with EtOAc. The organic layer was washed with brine, drying over anhydrous Na2SO4, then concentrated in vacuo. The residue was chromatographed on silica gel with hexane-EtOAc (1:5) as eluent to give methyl 4-[1-[4-[N′-(2-chlorophenyl)ureido]-3-methoxyphenyl acetyl]-5-(R)-phenyl-2-(S)-pyrrolidinylmethoxy]benzoate (260 mg, 90%) as a colorless amorphous solid. 1H-NMR (CDCl3) δ 2.00–2.19 (m, 3 H), 2.35–2.44 (m, 1 H), 3.35 (s, 2 H), 3.76 (s, 3 H), 3.89 (s, 3 H), 4.38–4.48 (m, 2 H), 4.63 (br s, 1 H), 4.94 (t, J=7.2 Hz, 1 H), 6.53 (d, J=8.4 Hz, 1 H), 6.66 (s, 1 H), 6.96–7.01 (m, 3 H), 7.12–7.42 (series of m, 8 H), 7.87 (d, J=8.0 Hz, 1 H), 7.98 (d, J=8.8 Hz, 2 H), 8.17–8.19 (m, 1 H); MS (ESI) m/z, 627(+), 628 (M++H).
