Coupling of 4-aminobenzyl alcohol (I) with diallyl L-glutamylisocyanate (II) produced the urea derivative (III). Subsequent activation of the benzylic alcohol group with 4-nitrophenyl chloroformate (IV) afforded carbonate (V). This was then condensed with doxorubicin (VI) to furnish the corresponding carbamate (VII). Finally, palladium-catalyzed cleavage of the allyl esters of (VII) yielded the title compound.
