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‐ 2 H 4 ]estrone ( 1 ) or [2,4,16,16,17‐ 2 H 5 ]estradiol ( 2 ) afforded [2,4,16,16‐ 2 H 4 ]estromustine ( 3 ) and [2,4,16,16,17‐ 2 H 5 ]estramustine ( 4 ), respectively. The phosphorylation of 4 followed by hydrolysis gave [2,4,16,16,17‐ 2 H 5 ]estramustine phosphate ( 5 ) in 65% chemical yield from 2 . Copyright © 2004 John Wiley & Sons, Ltd.
