Procedure

Benzyl 3-oxo-4-(pyridin-3-ylmethyl)piperazine-1-carboxylate (345 mg) was mixed with EtOH (7 ml), and 10% palladium carbon (70 mg) was added thereto under argon atmosphere to change the atmosphere to hydrogen atmosphere, followed by stirring at room temperature overnight. The reaction mixture was filtered using Celite as a filtration adjuvant, and the filtrate was concentrated under reduced pressure to obtain 1-(pyridin-3-ylmethyl)piperazin-2-one (190 mg).
