Reaction Steps

N-[3-(Dimethylamino)propyl]-5-isopropyl-2-{[(1-methyl-4-{[(1-methyl-4-nitro-1H-pyrrol-2-yl)carbonyl]amino}-1H-pyrrol-2-yl)carbonyl]amino}-1,3-thiazole-4-carboxamide (90 mg, 0.165 mmol; see step (v) above) was suspended in ethanol (20 mL) then Pd/C (97 mg, 10%) was added at 0° C. under nitrogen. The reaction mixture was hydrogenated at room temperature and atmospheric pressure for 5 h. The catalyst was removed under reduced pressure then ethyl formate (20 mL) was added to the ethanolic solution of the amine. The reaction mixture was heated under reflux for 3 days, then the solvent was removed under reduced pressure. The crude product was dissolved in water (2 mL) containing 0.1% TFA, then purified by HPLC. The fractions collected were freeze-dried to give the desired product as pale yellow solid (55 mg, 51%) with no distinct m.p.
