Versuchsvorschrift
1-Methyl-4-nitro-1H-pyrrole-2-carbaldehyde (0.400 g, 2.08 mmol; see step (i) above) was placed in 50 mL of anhydrous ethanol under N2. NaBH4 (0.040 g, 1.04 mmol) was added in small portions over 5 min and the solution allowed to stir for 20 min. Water (10 mL) was added slowly to quench the reaction. The organics were then extracted with ethyl acetate (2×20 mL) and the resultant organic fractions dried (MgSO4), filtered and the solvent removed under reduced pressure to yield the sub-title compound as a light brown solid (0.318 g, 98%).
