4-(TRIFLUOROMETHOXY)PHENACYL BROMIDE Chemical Properties,Usage,Production
Uses
2-Bromo-1-[4-(trifluoromethoxy)phenyl]ethan-1-one is an intermediate used to prepare aminothiazoles as therapeutic leads for prion diseases. It is also used in the synthesis of pyrrolidino-tetrahydroisoquinolines as potent dual H3 antagonist and serotonin transporter inhibitors.
Synthesis
85013-98-5
103962-10-3
General procedure for the synthesis of 2-bromo-1-[4-(trifluoromethoxy)phenyl]ethanone from 4'-(trifluoromethoxy)acetophenone: To a preheated (80 °C) stirred solution of copper(II) bromide (17.2 g, 77.2 mmol) in ethyl acetate (20 mL) was slowly added 4'-(trifluoromethoxy)acetophenone (8.7 g, 42.89 mmol) in a chloroform (10 mL) solution. The reaction mixture was stirred continuously at 80 °C for 4 h, during which the progress of the reaction was monitored by thin layer chromatography (TLC). Upon completion of the reaction, the reaction mixture was filtered through a diatomaceous earth pad to remove solid impurities. The filtrate was subsequently concentrated under reduced pressure to give the crude product. The crude product was further purified by silica gel column chromatography with an eluent of 2-2.5% dichloromethane/hexane mixed solvent, resulting in the target compound 2-bromo-1-[4-(trifluoromethoxy)phenyl]ethanone (7 g, 58.0% yield) as an off-white solid. Its 1H NMR (400 MHz, CDCl3) data were as follows: δ 8.05 (d, J=8.0 Hz, 2H), 7.32 (d, J=8.8 Hz, 2H), 4.41 (s, 2H).
