Brostallicin (PNU-166196A), a DNA minor groove binder, has been labelled with 2H and 14C. The preparation of the deuterium specifically labelled [2H4]brostallicin was achieved according to a nine-step sequence starting from 1,2-diamino[1,1,2,2-2H4]ethane (1). [14C]Brostallicin was obtained via a four-step procedure in 31% overall radiochemical yield starting from 1-methyl-4-nitropyrrole-2-[14C]carboxylic acid (9). Copyright © 2002 John Wiley & Sons, Ltd.
