실험 절차
1-Methyl-N-[2-(4-morpholinyl)ethyl]-4-nitro-1H-pyrrole-2-carboxamide (1.42 g, 3.41 mmol; see step (iii) above) was dissolved in methanol (10 mL) and cooled to 0° C., Pd/C (0.055 g) was then added in small portions and the solution stirred under H2 for 3 h. The solution was then filtered and the solvent removed under reduced pressure. A solution of 1-methyl-4-nitro-1H-pyrrole-2-carbonyl chloride (0.642 g, 3.42 mmol) in DCM (10 mL) was added and the mixture allowed to stir for 1 h at RT. The solvent was then removed under reduced pressure and the crude product was separated on basified silica using a 1:1 solution of methanol ethyl acetate to yield the sub-title compound.
