Procedure

Place 2-carboxymethoxy-5-iodo-benzoic acid (Preparation 21a; 7 g, 21 mmol) acetic anhydride (35 ml), sodium acetate (4 g), and acetic acid (5 mL) into a 50 mL round bottom flask. Heat the resulting mixture at 140° C. under stirring for 5 h and cool to room temperature. Add water (12 mL) into the mixture gradually maintaining the temperature below 60° C. and continue to stir for 18 h. Dilute with water (200 mL) and collect the resulting precipitate via vacuum filtration. Wash the solid with water and dry to give the final product (6 g, 95%). MS (electrospray, m/z) 303 (M+1).
