Reaction Steps

2-Methyl-1-(4-nitro-phenyl)-5-phenyl-1H-pyrrole-3-carboxylic acid ethyl ester of Example 33 (2 mmol, 0.8 g) was dissolved 50% solution of ethyl acetate in ethanol, and treated with Pd/C (0.088 g). The mixture was hydrogenated with H2(g) at 45 psi. Upon completion of the reaction, the mixture was filtered through Celite and the solvents removed under vacuum. This material was purified over silica gel to yield the named product.
