Production Methods

3-Aminophthalic acid (5.00 g, 27.6 mmol) was dissolved in 8.4 mol/L hydrochloric acid (60 mL), and the solution was added with an aqueous solution (10 mL) of sodium nitrate (2.0 g, 29 mmol) by drops under ice-cooling for 20 minutes, followed by stirring at the same temperature for 3 hours. Then, an aqueous solution (10 mL), in which potassium iodide (6.9 g, 41 mmol) and urea (291 mg) were dissolved, is added by drops to the mixture, followed by stirring at room temperature for 20 hours. The reaction mixture was added with 10percent aqueous sodium thiosulfate solution and extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure and the residue was washed with chloroform to obtain 3-iodophthalic acid (5.0 g, yield 62percent).[0030] The synthesis of mIBX is readily accomplished from commercially available 3-nitrophtalic acid as follows: esterification of 3-nitrophtalic acid via the corresponding acid chloride to give nitrodiester (100percent), which upon catalytic hydrogenation provides the aminodiester (100percent). Diazotization is then performed, followed by iodination of the aminodiester to provide dimethyl 3-iodophthalate in about 91 percent yield. This is followed by saponification, then acidification of dimethyl 3-iodophthalate to give 3-iodophthalic acid in about 93 percent yield. 3-iodophthalic acid is then oxidized to form the water-soluble MIBX.
