Reaktionsschritte

To a solution of 1,1-dimethylethyl 2-(4-(4-fluorophenyl)-1-piperazinyl)-2-oxo-1-(phenylmethyl)ethylcarbamate (2.7 g, 6.3 mmol) in ethyl acetate (20 mmol) under ice-cooling was dropwise added 4N HCl/ethyl acetate (20 ml), and the mixture was stirred at room temperature overnight. The resulting crystals were recovered by filtration and recrystallized from ethanol-diethyl ether to give 1-(2-amino-1-oxo-3-phenylpropyl)-4-(4-fluorophenyl)piperazine hydrochloride (2.2 g, 96.1%) as pale-yellow crystals.
