反応手順

1-Methyl-4-nitro-1H-pyrrole-2-carbonyl chloride (0.585 g, 4.70 mmol; see step (ii) above) in DCM (10 mL), was added dropwise to a solution of 2-(4-morpholinyl)ethanamine (0.673 g, 5.17 mmol), and NEt3 (0.735 μL, 9.42 mmol), in DCM (10 mL) over 15 min. The resulting solution was allowed to stir overnight and the reaction quenched with a 5% NaOH solution (20 mL). The layers were separated and the DCM fraction collected, dried (MgSO4), filtered and the solvent removed under reduced pressure to yield the sub-title compound as a white/pale yellow solid (1.166 g, 88%).
