The preparation of estromustine (EoM), estramustine (EaM) and estramustine phosphate (EMP) specifically labelled with deuterium is reported. A two-step, one-pot procedure based on the reaction of N,N-bis(2-chloroethyl)carbamoyl chloride with the commercially available [2,4,16,16-2H4]estrone (1) or [2,4,16,16,17-2H5]estradiol (2) afforded [2,4,16,16-2H4]estromustine (3) and [2,4,16,16,17-2H5]estramustine (4), respectively. The phosphorylation of 4 followed by hydrolysis gave [2,4,16,16,17-2H5]estramustine phosphate (5) in 65% chemical yield from 2. Copyright © 2004 John Wiley & Sons, Ltd.
