Reaktionsschritte

Platinum (IV) oxide (15 mg, 0.07 mmol) was added to a solution of 1-(3,4-dichlorobenzyl)-4-(2-nitrocyclohexyl)piperazine (187 mg, 0.50 mmol) in glacial acetic acid (5 ml). The reaction mixture was stirred under hydrogen atmosphere at room temperature for 16 h. The reaction mixture was then filtered through a pad of celite. The filtrate was made basic with a 15% sodium hydroxide solution and the product was extracted into ethyl acetate. The organic layer was dried over magnesium sulfate, filtered and concentrated in vacuo to provide 1-(3,4-dichlorobenzyl)-4-(2-aminocyclohexyl)-piperazine (119 mg) as an oil.
