Procedure

A suspension of (2-(4-bromo-2-fluoro-benzylcarbamoyl)-5-fluoro-4-morpholin-4-yl-phenoxy]-acetic acid ethyl ester (0.8 g, 1.73 mmol) in ethanol (9 mL) was treated with aq 2 N NaOH (5.0 mL, 10.4 mmol). After stirring for 30 min, the reaction was concentrated in vacuo until most of the ethanol was removed. The mixture was acidified to pH 3 with aq 2 N HCl, extracted with ethyl acetate, and washed with saturated NaCl. The organic layer was dried over MgSO4, filtered and concentrated to give [2-(4-bromo-2-fluoro-benzylcarbamoyl)-5-fluoro-4-morpholin-4-yl-phenoxy]-acetic acid (0.7 g, 93%) as a white crystalline solid: mp 180° C.; Rf 0.17 (20% methanol in dichloromethane); 1H NMR (DMSO-d6 300 MHz) δ 9.21 (t, J=5.4 Hz, 1 H), 8.17 (s, 1 H), 8.09 (dd, J, =8.1 Hz, J2=2.4 Hz, 1 H), 7.78 (d, J=7.5 Hz, 1 H), 7.65–7.52 (m, 2 H), 7.13 (d, J=13.8 Hz, 1 H), 4.85 (s, 2 H), 4.62 (d, J=6 Hz, 2 H), 3.71 (t, J=4.7 Hz, 4 H), 2.91 (t, J=4.8 Hz, 4 H). Anal. calcd for C20H20FN3O7: C, 55.43; H, 4.65; N, 9.70. Found C, 55.49; H, 4.68; N, 9.60.
