Product 1

HCID 60714Gadoteridol

Procedure

The solution of 1,4,7,10-tetraazacyclododecane-1,4,7-triacetic acid sodium salt is directly reacted, as described in EP 292689, with propylene oxide to give the alkylated product, which can easily be complexed with gadolinium to give the final Gadoteridol.
