Procedure

A mixture of 3-methoxy-4-[N′-(2-methylphenyl)ureido]phenylacetic acid (333 mg, 0.106 mmol), methyl 4-[(2S, 4S)4-(2-naphthyloxy)-2-pyrrolidinyl]methoxybenzoate (400 mg, 1.06 mmol), EDC.HCl (305 mg, 1.59 mmol) and DMAP (194 mg, 1.59 mmol) in DMF (10 ml) was stirred at room temperature for 3 days. The mixture was poured into ice water and extracted with EtOAc. The combined extracts were washed with ice water and brine. After dried over Na2SO4, the extracts were concentrated in vacuo. The residue was chromatographed on silica gel [100 g, n-hexane/EtOAc(1/1)CHCl3/MeOH(50/1)], to give methyl 4-[(2S, 4S)-1-[3-methoxy-4-[N′-(2-methylphenyl)ureido]phenylacetyl]-4-(2-naphthyloxy)-2-pyrrolidinyl]methoxybenzoate (520 mg, 73%) as a pale brown amorphous. 1H-NMR (CDCl3) δ 2.28 (s, 3H), 2.29 (m, 1H), 2.55 (d, J=14.2 Hz, 1H), 3.60 (d, J=3.4 Hz, 2H), 3.66 (d, J=3.7 Hz, 3H), 3.68–4.00 (m, 5H), 4.05–4.67 (m, 3H), 5.09 (br, 1H), 6.61 (s, 1H), 6.77 (m, 2H), 6.87 (d, J=8.8 Hz, 1H), 6.94–7.54 (m, 8H), 7.68–8.09 (m, 8H); MS (ESI) m/z 674 (M++1).
