YieldReaction ConditionsOperation in experiment
With phosphorus tribromide; In tetrachloromethane; PREPARATION 14 Preparation of 3,4-dichlorophenethyl bromide STR37 Phosphorus tribromide (2.17 g) was added, dropwise, to a solution of <strong>[35364-79-5]3,4-dichlorophenethyl alcohol</strong> (4.26 g) in carbon tetrachloride (30 ml). The mixture was stirred at room temperature for 10 minutes then heated under reflux for 2 hours. 5% Aqueous sodium carbonate (10 ml) was added dropwise and the mixture was extracted with dichloromethane (3*70 ml). The combined dichloromethane extracts were dried (MgSO4) and concentrated in vacuo to give a yellow oil which was purified by column chromatography on silica eluding with dichloromethane containing hexane (30% down to 0%). The product-containing fractions were combined and concentrated in vacuo to give the title compound as a colourless oil, yield, 1.8 g. 1 H-N.M.R. (CDCl3) delta=7.50-7.30 (m, 2H); 7.15-7.05 (m, 1H); 3.65-3.50 (t, 2H); 3.20-3.10 (t, 2H) ppm.

YieldReaction ConditionsOperation in experiment
33% With carbon tetrabromide; triphenylphosphine; In dichloromethane; at 20℃; 2-(3,4-Dichlorophenyl)ethan-1-ol (500 mg, 2.62 mmol), 27 triphenylphosphine (1.03 g, 3.93 mmol) and 28 tetrabromomethane (1.30 g, 3.93 mmol) were dissolved in 29 dichloromethane (20 mL). The reaction mixture was stirred for overnight in the room temperature. The reaction mixture was concentrated under reduced pressure. The residue was purified on an ISCO chromatography (0-10% ethyl acetate/hexane) to give the 20 product as colorless oil (219 mg, 33%); 1H NMR (300 MHz) (CDCl3) delta 7.39 (d, J=8 Hz, 1H), 7.31 (d, J=2 Hz, 1H), 7.06 (dd, J=8 Hz, J=2 Hz, 1H), 3.54 (t, J=7 Hz, 2H), 3.12 (t, J=7 Hz, 2H).
