Procedure

To a stirred solution of dimethyl (S)-4-(2-pyrrolidinylmethoxy)isophthalate (616 mg, 2.10 mmol) in DMF (13 mL) was added pentafluoro ester of 3-methoxy4-[N′-(2-methylphenyl)ureido]phenylacetic acid (1.00 g, 2.08 mmol) and Et3 N (425 μl, 3.12 mmol), and the resulting mixture was stirred for 3.5 hr at room temp. The resulting mixture was diluted with EtOAc, washed with 1 N HCl, sat. NaHCO3, brine, and dried over Na2SO4. After removal of the solvent, the residue was purified by column chromatography on silica-gel with CHCl3-MeOH (50:1, v/v) as eluent to give 1.41 g(q.y.) dimethyl (S)-4-[1-[3-methoxy-4-[N′-(2-methylphenyl)ureido]phenylacetyl]-2-pyrrolidinylmethoxy]isophthalate as a yellow oil. 1H-NMR (CDCl3) δ 1.86–2.29 (m, 4 H), 2.30 (s, 3 H), 3.47–3.57 (m, 2 H), 3.58 (s, 3 H), 3.59 (s, 2 H), 3.83 (s, 3 H), 3.91 (s, 3 H), 4.22–4.37 (m, 2 H), 4.42–4.47 (m, 1 H), 6.44–8.46 (series of m, 12 H).
