Reaction Steps

To an aqueous solution of 1-[10-(3,5-dicarboxyphenyl)decyl]-1,4,7,10-tetraazacyclododecane (0.16 mols in 500 mL water) is added an aqueous solution of sodium chloroacetate (0.71 mols sodium chloroacetate in 68 mL of water). This solution is stirred at 80° C. overnight while maintaining the pH at 9-10. After cooling to ambient temperature the pH of the solution is adjusted to 2.5 with aqueous HCl. The resulting precipitate is collected by filtration, washed with acetone, and dried in vacuo to afford 18.
