Procedure

A mixture of methyl 4-(4,4-difluoro-2-pyrrolidinylmethoxy)benzoate (540 mg, 1.99 mmol), 3-methoxy-4-[N′-(2-methylphenyl)ureido]phenylacetic acid (626 mg, 1.99 mmol), EDC.HCl (572 mg, 2.99 mmol), HOBt (cat.), and DMAP (cat.) in DMF (10 ml) was stirred overnight. The mixture was diluted with EtOAc (300 ml), washed with brine (2×100 ml), dried over MgSO4, and concntrated in vacuo. The residue was chromatographed on silica gel with CHCl3—MeOH (20:1) as eluent to give methyl 4-[4,4-difluoro-1-[3-methoxy-4-[N′-(2-methylphenyl)ureido]phenylacetyl]-2-pyrrolidinylmethoxy]benzoate (1.00 g, 89%) as a colorless foam. 1H-NMR (CDCl3) δ2.31 (s, 3 H), 2.47-2.63 (m, 2 H), 3.52-3.97 (series of s and m, total 10 H), 4.07-4.30 (m, 2 H), 4.67-4.69 (m, 1 H), 6.45 (s, 1 H), 6.65 (d, J=1.7 Hz, 1 H), 6.74-6.76 (m, 1 H), 6.84 (d, J=8.8 Hz, 2 H), 7.14 (m, 2 H), 7.24 (m, 2 H), 7.52-7.54 (m, 1 H), 7.94 9d, J=8.8 Hz, 2 H), 8.09 (d, J=8.1 Hz, 1 H).
