Acylation of the tertiary 20-hydroxy group of camptothecin (I) with N-Boc-valine-N-carboxyanhydride (II) afforded the corresponding ester (III). Subsequent acidic N-Boc group cleavage gave amino ester (IV). This was coupled with N-Boc-histidine (V) to furnish, after treatment with trifluoroacetic acid, the histidyl-valyl camptothecin ester (VI).
