실험 절차

A mixture of Example 26 (283.7 mg, 0.59 mmol), 10% Pd/C (282 mg) and acetic acid (3 drops) in 30 mL of [DMF:MeOH=1:1] was stirred at r.t under H2 atmosphere. After the reaction was complete as detected by LC/MS, the catalyst was filtered off and the filtrate was evaporated to dryness. The residue was triturated with ethanol to provide 5-[5-Fluoro-2-oxo-1,2-dihydro-indol-(3Z)-ylidenemethyl]-2,4-dimethyl-1H-pyrrole-3-carboxylic acid (4-hydroxy-pyrrolidin-3-yl)-amide (178 mg, 67%).
