Reaction Steps

A mixture of 5-bromomethyl-2-propionylamino-benzoic acid methyl ester (200 mg, 0.67 mmol), 2,4-dichloro-phenol (119 mg, 0.73 mmol) and potassium carbonate (278 mg, 2.01 mmol) in acetone (5 ml) was heated to reflux. After 4 hours, the reaction mixture was allowed to reach room temperature, was acidified with 1 M HCl and the resulting precipitate collected by filtration, washed with water and dried under vacuum to give pure 5-(2,4-dichloro-phenoxymethyl)-2-propionylamino-benzoic acid methyl ester (184 mg, 72%). This was hydrolyzed in ethanol (3 mL) and 1.0 M NaOH (3 mL) overnight and then acidified with 1.0 M HCl. The resulting precipitate was collected by filtration, washed with water and dried under vacuum (165 mg, 93%). 1H-NMR (DMSO-d6) δ 1.12 (t, 3H), 2.42 (q, 2H), 5.21 (s, 2H), 7.27 (d, 1H), 7.39 (dd, 1H), 7.60 (d, 1H), 7.66 (dd, 1H), 8.09 (d, 1H), 8.53 (d, 1H), 11.18 (s, 1H), 13.71 (bs, 1H).
