1-(3-(Trifluoromethyl)phenyl)piperazine → HCID 76283157, compound

Participants

Reaction Steps

1-(4-chlorobutyl)-5,6-dimethyl-1H-benzotriazole (8.56 g, 0.036 mol) was dissolved into 100 ml of acetonitrile, 3-trifluoro methylphenylpiperazine (6.9 g, 0.03 mol), diisopropylethylamine (15.5 g, 0.12 mol) and potassium iodide (5.0 g, 0.03 mol) were respectively added. The mixture was stirred and mixed, then heated and refluxed to react for 15 hours. The mixture was cooled down to ambient temperature and filtered. The filtrate was concentrated to produce oily products, and treated by chromatography with neutral Al2O3 and purified, eluted with dichloromethane to produce 9.1 g compound (I-33) with a yield of 70.3%. ESI-MS [M+H]+: m/z 432.2.
