Procedure

To a solution of ethyl 3-(1-(4-cyano-2-methylphenyl)-1H-pyrrol-2-yl)acrylate (6C) (8.0 g, 28.6 mmol) in ethanol was added 10% Pd/C (0.8 g). The mixture was stirred under 1 atm of H2 for 30 min at room temperature and filtered. The resultant filtrate was concentrated to dryness affording the crude product of ethyl 3-(1-(4-cyano-2-methylphenyl)-1H-pyrrol-2-yl)propanoate (7.5 g), which was used for the next step without further purification: LC-MS m/z 283.0 [M+H]+, purity 68%.
