Procedure

Pyrrolidine-1-carboxylic acid [4-(4-nitrophenoxy)pyridin-2-yl]amide (116.8 mg) was dissolved in tetrahydrofuran (3 ml), 20% palladium hydroxide on carbon (25.0 mg) was added under a nitrogen atmosphere at room temperature while stirring, followed by stirring under a hydrogen atmosphere for 7 hr. The atmosphere in the reaction vessel was replaced with nitrogen, and the catalyst was removed by filtration and washed with tetrahydrofuran. The solvent was removed under reduced pressure to provide the titled compound as a pale yellow solid (112 mg).
