A synthesis of [3H]-KW-2189 has been published: The condensation of duocarmycin B2 (I) with tert-butoxycarbonylpiperazine (II) and 4-nitrophenyl chloroformate by means of triethylamine in dichloromethane gives the expected piperazinecarboxylate (III), which is reduced with NaBH4 in allyl alcohol to yield the hydroxy-derivative (IV). The treatment of (IV) with camphorsulfonic acid (CSA) in hot toluene affords the isomerized compound (V) along with simultaneous deprotection of the piperazine ring. Finally, compound (V) is methylated with tritiated methyl iodide and NaHCO3 in acetone/methanol.
