The benzoylation of 1,3,5(10)-estratrien-3,17beta-diol (I) with benzoyl chloride (II) by means of NaOH in THF-water gives 3-benzoyloxy-1,3,5(10)-estratrien-17beta-ol (III), which is acylated with bromoacetyl bromide (IV) by means of pyridine in THF-CCl4 yielding 3-benzoyloxy-17beta-bromoacetoxy 1,3,5(10)-estratriene (V). Finally, this compound is condensed with silver 4-[4-[bis(2-chloroethyl)amino]phenyl]butyrate (VI) in DMSO.
