inhibitor that is under development by Millennium in clinical studies in both hematologic and nonhematologic malignancies. The stable isotope-labeled MLN9708 was required for bio-analytical studies. [(13) C9 ]-MLN9708 (11) was synthesized in seven steps from the uniformly labeled [(13) C6 ]-1,4-dichlorobenzene (3) and [1-(13) C]-acetyl chloride. Because of the presence of two chlorine atoms and a boron atom
