To a stirred solution of benzyl 4-[N′-(2-fluorophenyl)ureido]-3-methoxyphenylacetate (2.04 g, 5 mmol) in THF (40 mL) was added 0.25 N NaOH (40 mL). The resulting mixture was stirred overnight. The mixture was poured into 1 N HCl (10 mL), and the resulting precipitate was collected with suction. The residue was recrystallized from CHCl3-EtOH to give 1.04 g (66%) 4-[N′-(2-fluorophenyl)ureido]-3-methoxyphenylacetic acid as a white crystalline powder. mp 185 –188 (d); 1H-NMR (DMSO-d6) δ 3.50 (2H, s), 3.82 (3H, s), 6.78 (1H, dd, J=1.4 and 8.3 Hz), 6.92 (1H, d, J=1.4 Hz), 6.95–7.01 (1H, m), 7.10–7.14 (1H, m), 7.19–7.24 (1H, m), 8.01 (1H, d, J=8.3 Hz), 8.14–8.18 (1H, m), 8.72 (1H, s), 9.17 (1H, s); MS (FAB) m/z 319 (M++1); Anal.
