With iodine; magnesium; In tetrahydrofuran; hydrogenchloride; hexane; ethyl acetate; Preparation 15 A mixture of <strong>[139155-55-8]1-bromo-3-isobutylbenzene</strong> (3.16 g), magnesium (1.08 g), 1,2-dibromoethane (2.78 g) and iodine (10 mg) in tetrahydrofuran (10 ml) was refluxed for 1.5 hours. The mixture was cooled to 25 C., and a solution of 3-isobutylbenzaldehyde (2.40 g) in tetrahydrofuran (10 ml) was added at 25 C. After stirred for 1 hour at the same temperature, the mixture was poured into a mixture of ethyl acetate and 1N hydrochloric acid. The organic layer was separated, washed with water and brine, and dried over magnesium sulfate. After evaporation of the solvent, the residue was chromatographed on silica gel (200 g) eluding with 5% ethyl acetate in hexane to give bis(3-isobutylphenyl)methanol (2.90 g) as a colorless oil. NMR (CDCl3, delta): 0.89 (12H, d, J=7.5 Hz), 1.70-1.95 (2H, m), 2.46 (4H, d, J=7.5 Hz), 5.80 (1H, s), 6.97-7.09 (2H, m), 7.09-7.30 (6H, m)

With copper(I) bromide; In hydrogen bromide; Preparation 14 To a solution of 3-isobutylphenylamine (3.80 g) in 48% hydrobromic acid (10 ml) was added aqueous sodium nitrite (2.11 g, 2 ml) below 10 C. over 20 minutes. The reaction mixture was added to a solution of cuprous bromide (7.3 g) in 48% hydrobromic acid (5 ml) at 25 C. After stirred at 25 C. for 1 hour, the mixture was extracted with hexane two times. The extracts were combined, washed with water and brine, and dried over magnesium sulfate. After evaporation of the solvent, the residue was chromatographed on silica gel (150 g) eluding with hexane to give 1-bromo-3-isobutylbenzene (2.61 g) as a colorless oil.

YieldReaction ConditionsOperation in experiment
42% lsobutylmagnesium bromide (2M in diethyl ether, 26.5ml, 53mmol) was added over 30 minutes at room temperature to a solution of 1-bromo-3-iodobenzene (1Og, 35.3mmol) and tetrakis(triphenylphosphine)palladium (0) (1.1 g, 0.954mmol) in toluene (160ml). The reaction mixture became green and the temperature was not allowed to rise above 400C. The reaction mixture was then stirred at room temperature for three hours. Aqueous ammonium chloride solution (160ml) was then added (the reaction became red) and the mixture was extracted with diethyl ether (2x100ml). The organics were washed with more ammonium chloride (100ml), dried over magnesium sulphate and concentrated under reduced pressure. The crude product was then purified by distillation to provide the title compound (boiling point 88C under 25mmHg, 3.2Og, 42%). 1H-NMR (400MHz, CDCI3) : delta = 0.90 (d, 6H), 1.85 (m, 1 H), 2.44 (d, 2H), 7.07 (d, 1 H), 7.14 (t, 1 H)1 7.30 (m, 2H).

57% n-Butyl lithium (2.5M in hexanes, 6.4ml, 16.0mmol) was added dropwise over 10 minutes at 00C to a solution of the bromobenzene of Preparation 4 (3.11 g, 14.6mmol) in diethyl ether (30ml). The reaction mixture was stirred at O0C for 15 minutes and then dry N,N-dimethylformamide (1.13ml, 14.6mmol) was added at O0C. The reaction was stirred at O0C for ten minutes, at room temperature for ten minutes and then heated under reflux for four hours. After cooling, the reaction was quenched with water (25ml). The organic phase was separated and the aqueous phase was extracted with more diethyl ether (25ml). The organic phases were combined, washed with water (25ml), dried over magnesium sulphate and concentrated under reduced pressure. The crude product was purified by flash chromatography on silica gel eluting with ethyl acetate: heptane (0:100 to 10:90, by volume) to provide the title compound (1.35g, 57%) as a yellow oil.
