Procedure

To a mixture of 5-hydroxyisophthalic acid dimethyl ester (500 mg, 2.38 mmol) and chloroacetamide (245 mg, 2.62 mmol) in DMF (7 mL) is added potassium carbonate (986 mg, 7.14 mmol) and the mixture is stirred at room temperature for 2 days. Water is added to the mixture and then it is extracted with ethyl acetate. The organic phase is washed with water and brine and is dried over sodium sulfate. The organic solution is concentrated to one fourth volume to give a precipitate. The solid is filtered, washed with ethyl acetate and dried under reduced pressure to give 5-carbamoylmethoxyisophthalic acid dimethyl ester. MS 268.2 (M+1); 1H-NMR (400 MHz, CDCl3); δ ppm 3.96 (s, 6H), 4.59 (s, 2H), 5.87 (s, broad, 1H), 6.55 (s, broad, 1H), 7.79 (s, 2H), 8.37 (s, 1H).
