Reaction Steps

In a flame dried round-bottomed flask equipped with a magnetic stir bar and under inert atmosphere (N2), to a solution of 1-acetylpiperazine (256 mg, 2.00 mmol) and DBU (0.30 mL, 2.00 mmol) in dry Et2O (2 mL) was added 4-bromobutyronitrile (0.21 mL, 2.00 mmol) at 0° C. The reaction mixture was stirred at rt until completion of the reaction. The mixture was filtered and concentrated under reduced pressure. A 0.087 mol/L solution of the crude nitrile in EtOH (10 mL) was hydrogenated at 50° C. using the H-Cube® (1 mL/min) with a Raney Nickel cartridge (30 mm) under 50 bar until completion of the reaction. The solution was then concentrated under reduced pressure to give crude 1-(4-(4-aminobutyl)piperazin-1-yl)ethanone as a colorless oil. GC-MS-conditions 01: tR=2.94 min; [M+H]+=200.40.
