실험 절차

A mixture of 3-methoxy-4-[N′-(2-methylphenyl)ureido]phenylacetic acid (375 mg, 1.19 mmol), methyl 4-[(2S,4S)4-methoxy-2-pyrrolidinyl]methoxybenzoate (317 mg, 1.19 mmol), EDC.HCl (342 mg, 1.79 mmol), HOBT (242 mg, 1.79 mmol) and Et3 N (0.83 ml, 5.95 mmol) in DMF (5 ml) was stirred at room temperature for 13 h. 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 [50 g, CHCl3/Aectone (10/1)CHCl3/MeOH (20/1)], to give methyl 4-[(2S,4S)-4-methoxy-1-[3-methoxy-4-[N′-(2-methylphenyl)ureido]phenylacetyl]-2-pyrrolidinyl]methoxybenzoate (650 mg, 98%) as a pale brown amorphous solid 1H-NMR (CDCl3) δ 2.03 (m, 1H), 2.31 (s, 3H), 2.32 (m, 1H), 3.29 (d, J=1.0 Hz, 3H), 3.57–3.68 (m, 5H), 3.88 (d, J=1.0 Hz, 3H), 3.99–4.06 (m, 2H), 4.46 (m, 1H), 6.19 (m, 1H), 6.80 (s, 1H), 6.81 (d, J=9.0 Hz, 1H), 6.96–7.19 (m, 4H), 7.29 (m, 2H), 7.50 (d, J=6.7 Hz, 1H), 7.95–8.10 (m, 3H); MS (ESI) m/z 562 (M++1).
