Procedure

To a solution of 4-(1-methyl-azetidin-3-yl)piperazine-1-carboxylic acid [4-(2-fluoro-4-nitrophenoxy)pyridin-2-yl]amide (121 mg) in tetrahydrofuran (50 ml) was added 20% palladium hydroxide carbon (91.3 mg), followed by stirring under a hydrogen atmosphere at room temperature for 12 hrs. The reaction mixture was filtered to remove the catalyst, and the catalyst was washed with tetrahydrofuran:methanol=1:1. The filtrate was concentrated to provide the titled compound (113 mg, 100%) as a yellow amorphous substance.
