Reaction Steps

10% Pd/C (1.6 g) was added to a solution of 10-[2-[bis[2-[(1-oxohexadecyl)oxy]ethyl]amino]-2-oxoethyl]-1,4,7,10-tetraazacyclo-dodecane-1,4,7-triacetic acid tris(phenylmethyl)ester (16 g; 12.9 mmol) in EtOH (500 mL) and the suspension was stirred for 12 h under hydrogen atmosphere at room temperature. After filtration through a Millipore® filter FT 0.45 μm the solution was evaporated under reduced pressure to give the desired compound. Yield 93%. HPLC: 98% (area %). The 13C-NMR, MS and IR spectra were consistent with the structure.
