Procedure

A solution of methyl 4-[1-[4-[N′-(2-benzyloxyphenyl)ureido]-3-methoxyphenylacetamido]-2-pyrrolidinylmethoxy]-3-nitrobenzoate (1.52 g, 2.27 mmol) in MeOH (20 mL) and THF (5 mL) was hydrogenated over 5% Pd—C (wet, 52.2%; 1.21 g) under hydrogen atmosphere (4 kg/cm2) at room temperature After being stirred for 17 hr, the catalyst was filtered off and the filtrate was concentrated to dryness. Chromatography of the residue with EtOAc as eluent gave methyl 3-amino-4-[1-[4-[N′-(2-hydroxyphenyl)ureido]-3-methoxyphenylacetamido]-2-pyrrolidinylmethoxy]benzoate (1.12 g, 90%) as a brownish amorphous solid. 1H-NMR (CDCl3) δ 1.97–2.10 (m, 4H), 3.44 (s, 3H), 3.52–3.63 (m, 2H), 3.85 (s, 3H), 4.10–4.18 (m, 2H), 4.53 (m, 1H), 6.65–6.67 (m, 4H), 6.93–7.02 (m, 3H), 7.33 (d, J=2.2 Hz, 1H), 7.36 (dd, J=8.3, 2.2 Hz, 1H), 7.60 (s, 1H), 7.69 (d, J=8.3 Hz, 1H), 8.08 (s, 1H), 9.47 (broad s, 1H); FAB-MS m/z 549 (M++1).
