Procedure

A solution of methyl 4-(2-(3-methylpyridylureido)phenylacetate (1 eq.) in methanol was treated with 1 N NaOH (2 eq.). The reaction was stirred for 16 h, then acidified carefully with 1 N HCl to pH 7 then with acetic acid to pH 3. The product was filtered and washed with methanol then ether to give 4-(2-(3-methylpyridylureido)phenylacetic acid: 1H NMR (CD3SOCD3, 300 MHz, ppm) 11.97 (s, 1H), 8.64 (brs, 1H), 8.31 (s, 1H), 7.69 (m, 1H), 7.62 (d, 8.4 Hz, 2H), 7.33 (d, 8.4 Hz, 2H), 7.09 (m, 1H), 3.62 (s, 2H), 2.38 (s, 3H); m/z 286.
