Reaction Steps

1-Methyl-4-{[(1-methyl-4-nitro-1H-pyrrol-2-yl)carbonyl]amino}-N-[2-(4-morpholinyl)ethyl]-1H-pyrrole-2-carboxamide (86 mg, 0.212 mmol; see Preparation 1 (iv) above) was suspended in methanol (25 mL) to which Pd/C-10% (80 mg) was added at 0° C. under nitrogen with stirring. The reaction mixture was hydrogenated for 4 h at room temperature and atmospheric pressure. The catalyst was removed over Kieselguhr and methanol was removed under reduced pressure to give the amine, which was dissolved in DMF (1 mL, dry). The resulting amine was utilised in the next step without purification.
