Procedure

The mixture of pentafluorophenyl 3-methoxy-4-[N′-(2-methylphenyl)ureido]phenylacetate (500 mg, 1.04 mmol), methyl 3-chloro-4-(2-pyrrolidinyl)methoxybenzoate (281 mg, 1.04 mmol), Et3N (0.17 mL, 1.25 mmol) in DMF (5 mL) was stirred for 1 hr at room temp. The mixture was diluted with EtOAc, washed with brine, and dried over Na2SO4. The solvent was removed under a reduced pressure, and the residue was chromatographed on silica-gel with n-hexane-EtOAc (1:3, v/v) as eluent to afford methyl 3-chloro-4-[[1-[3-methoxy-4-[N′-(2-methylphenyl)ureido]phenylacetyl]-2-pyrrolidinyl]methoxy]benzoate (620 mg, 1.04 mmol) as a white crystalline solid. To a stirred solution of this compound in THF (8 mL) and H2O (2 mL) was added LiOH (74.9 mg, 3.126 mmol), and the mixture was stirred at room temp for 2 days. The mixture was diluted with CHCl3, and treated with 1N HCl. The solution was washed with brine, dried over Na2SO4, and evaporated in vacuo. The crude solid was recrystallized from n-hexane-EtOAc—CHCl3 to afford 561.2 (98%) 29 as a white crystalline material.
