83% | In water; acetonitrile; | C/ Preparation of 1-(2'-bromophenyl)-1-methyl-ethylamine: The preceding derivative, dissolved in a water/acetonitrile mixture (50/50, 60 ml), was added all at once to bis(trifluoroacetoxy)iodosobenzene (10.88 g; 25.3 mmole). The reaction mixture was stirred at room temperature for 24 h. After addition of water (450 ml), stirring was continued for 30 min more. Tertiobutylmethylether (150 ml) was added to the reaction mixture and the latter was decanted. The organic phase was extracted with a 10% hydrochloric acid solution then the aqueous phase was washed with 3*150 ml of tertiobutylmethylether. The aqueous phase was alkalinised (12 |

32% | With potassium carbonate; In tetrahydrofuran; at 50 - 55℃; for 16h; | tert-Butyl 2-bromoacetate (6.24 mL, 42.2 mmol) was slowly added to a solution of <strong>[173026-23-8]2-(2-bromophenyl)propan-2-amine</strong> (9.04 g, 42.22 mmol) and potassium carbonate (14.6 g, 105.6 mmol) in dry tetrahydrofuran (100 mL) at 0 C. and reaction mixture was stirred at 50-55 C. for 16 hours. Once cooled to room temperature, reaction mixture was diluted with brine (100 mL) and extracted using ethyl acetate (3×100 mL). The organic layers were combined, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel chromatography, eluting from 0% to 20% ethyl acetate in heptanes to afford tert-butyl 2-[2-(2-bromophenyl)propan-2-yl]amino}acetate (4.5 g, 32% yield) as a yellow oil. 1H NMR (300 MHz, CDCl3) ppm 1.43 (s, 9H), 1.63 (s, 6H), 2.94 (s, 2H), 7.09 (dt, J=7.6, 1.7 Hz, 1H), 7.22-7.31 (m, 1H), 7.43 (dd, J=7.9, 1.6 Hz, 1H), 7.58 (dd, J=7.9, 1.4 Hz, 1H).

77% | Methylmagnesium bromide (54.9 mL, 164.8 mmol, 3M in diethyl ether) was added to a solution of 2-bromobenzonitrile (10.0 g, 54.9 mmol) in diethyl ether (200 mL) and the reaction mixture was stirred at room temperature under nitrogen. After 30 minutes, titanium isopropoxide (16.3 mL, 54.9 mmol) was added and resulting mixture was refluxed overnight. Once cooled to 0 C., 2N NaOH (400 mL) was added and resulting mixture was stirred at room temperature for 30 minutes. The solution was diluted with saturated aqueous sodium bicarbonate (400 mL), extracted using methyl tert-butyl ether (3×200 mL). The organic layers were combined and concentrated under reduced pressure. The residue was dissolved in 1N hydrochloric acid (75 mL) and washed with methyl tert-butyl ether (150 mL). The aqueous layer was basified to pH 10-11 using 2N sodium hydroxide and the resulting solution was extracted with methyl tert-butyl ether (3×200 mL). The organic layers were combined, dried over anhydrous sodium sulfate and concentrated under reduced pressure to afford 2-(2-bromophenyl)propan-2-amine (9.0 g, 77% yield) as orange oil. 1H NMR (300 MHz, CDCl3): ppm 1.66 (s, 6H), 7.02-7.10 (m, 1H), 7.13-7.43 (m, 1H), 7.55-7.61 (m, 2H).

General procedure: To a toluene solution (6 mL) of 2-(2-fluorophenyl)propane-2-ol (925 mg) while stirring, trimethylsilyl azide (830 mg) and boron trifluoride-diethyl ether complex (1021 mg) were sequentially dropped, and stirred for 15 minutes at room temperature. After disappearance of starting materials was verified, a saturated aqueous solution of sodium hydrogen carbonate (50 mL) was added to the reaction solution, and the product was extracted with ethyl acetate (40 mL). The organic layer was dried with anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The obtained residue was dissolved in THF (15 mL), the solution was gradually dropped into a THF suspension (15 mL) of lithium aluminium hydride (228 mg) at room temperature. After stirring for 2 hours, to the reaction solution, water (230 muL), a 2 mol/L sodium hydroxide aqueous solution (230 muL), and water (690 muL) were gradually and sequentially dropped to the reaction solution. After being filtered with Celite, the mixture was concentrated under reduced pressure. The obtained residue was purified with silica gel column chromatography (chloroform/methanol=92/8 to 85/15) to give 2-(2-fluorophenyl)propane-2-amine (410 mg) as an oil. 1H NMR (300 MHz, CDCl3) delta 1.55 (s, 6H), 6.99-7.12 (m, 2H), 7.18-7.27 (m, 1H), 7.41-7.46 (m, 1H) |
