実験手順

4-(Pyrrolidin-1-ylmethyl)piperidine-1-carboxylic acid [4-(4-nitrophenoxy)pyridin-2-yl]amide (295 mg) was dissolved in tetrahydrofuran (7 ml) and methanol (7 ml) under a nitrogen atmosphere, and then 10% palladium carbon (147 mg) was added, followed by stirring under a hydrogen atmosphere for 10 hrs. The reaction mixture was filtered to remove the catalyst, and the catalyst was washed with methanol. The filtrate was concentrated to give a residue, which was then purified by silica gel column chromatography (Fuji Silysia NH, eluent; ethyl acetate). Fractions containing a target compound were concentrated to provide 4-(pyrrolidin-1-ylmethyl)piperidine-1-carboxylic acid [4-(4-aminophenoxy)pyridin-2-yl]amide (233.7 mg) as white foam.
