実験手順
2-Amino-1-(4-benzyl-piperazin-1-yl)-(S)-3-phenyl-propan-1-one hydrochloride (500 mg, 1.26 mmol) were dissolved in MeOH (5 mL), DIPEA (359 mg, 2.77 mmol) and 4-n-butoxybenzaldehyde (226 mg, 1.26 mmol) was added and the mixture was heated to reflux for 2 h, cooled again to rt followed by slow addition of sodium borohydride (48 mg, 1.26 mmol) in portions. Stirring was continued for 15 min. Water (1 mL) was added and the solvents were removed under reduced pressure. The residue was taken up in diethylether (5 mL), washed with 10% aq. citric acid (5 mL) and water (5 mL), dried over magnesium sulfate, filtered and concentrated in vacuo to give 411 mg (67%) of 1-(4-benzyl-piperazin-1-yl)-2-(4-butoxy-benzylamino)-(S)-3-phenyl-propan-1-one. LC-MS: tR=0.74 min; [M+H]+=486.43.
