실험 절차

4-[2-(Azetidin-1-yl)ethyl]piperazine-1-carboxylic acid [4-(4-nitrophenoxy)pyridin-2-yl]amide (122 mg) was dissolved in tetrahydrofuran (3 ml) and methanol (3 ml). 10% Palladium carbon (61 mg) was added, followed by stirring under a hydrogen atmosphere for 22 hrs. The reaction mixture was filtered to remove the catalyst, and the catalyst was washed with methanol. The filtrate was concentrated under reduced pressure to give a residue, which was then purified by silica gel column chromatography (Fuji Silysia NH, eluent; ethyl acetate:methanol=9:1). Fractions containing the target compound were concentrated to give a crude product of the titled compound (70 mg) as a pale yellow oil.
