Procedure

12.72 g (18.2 mmol) of 2-[4-hydroxybenzyl)-1,4,7,10-tetrakis-(tert-butoxycarbonylmethyl)-1,4,7,10-tetraazacyclododecane (example 9d) is dissolved in 250 ml of toluene and mixed with 350 mg of sodium hydride (80% in paraffin, 18.3 mmol). It is warmed to 80° to 100° C. and mixed by instillation with a solution of 1.74 g (18.2 mmol) of epichlorohydrin in 50 ml of toluene. After refluxing for two hours, it is concentrated by evaporation and purified over a silica gel column. A colorless oil is obtained.
