Reaction Steps
The solution of 1,4,7,10-tetraazacyclododecane-1,4,7-triacetic acid sodium salt is directly reacted, as described in EP 448191, with 4,4-dimethyl-3,5,8-trioxabicyclo[5.1.0]octane to give the alkylated product, which can easily be complexed with gadolinium to give the final Gadobutrol.
