Hydrazine (5 eq) was added to a solution of (tert-butoxy)-N-{1-[3-(1,3-dioxobenzo[c]azolin-2-yl)propyl]-4-(4-ethylphenyl)pyrrol-3-yl}carboxamide (1 eq) in abs. EtOH at 50° C. for 2 hours. The reaction developed a white precipitate which was filtered off. The EtOH was concentrated under reduced pressure. The residue was taken up in CH2Cl2 and the precipitate was filtered again.
