実験手順

A reactor was charged with 20 g (0.04 mole) of 11,15-dihydroxy-13-sulfoethyl-9,13,17-triazapentacosane and 100 g of xylene, to which 10 g (0.1 mole) of maleic anhydride were then added with stirring to conduct a reaction at 50° C. for 6 hours. After xylene was distilled off under reduced pressure, 300 ml of water were added, and 10% sodium hydroxide was further added to keep the pH of the reaction mixture at 7. Thereafter, the reaction mixture was subjected to electrodialysis and lyophilized, thereby obtaining 22 g (isolation yield: 80%) of 6,10-dihydroxy-4,12-dioctyl-3,13-dioxo-8-sulfoethyl-4,8,12-triaza-1,14-pentadecadiene-1,15-dicarboxylic acid as white powder.
