With hydrogenchloride; ammonium chloride; magnesium; | i) To a suspension of magnesium turnings (0.55 g.) in dry ether (20 ml.) was added dropwise a solution of methyl iodide (3 g.) in dry ether (10 ml.) at such a rate that the reaction refluxed. After the addition was complete, <strong>[56961-76-3]3,4,5-trichlorobenzaldehyde</strong> (see Process B) (4 g.) was added in dry ether (10 ml.) at a rate that maintained reflux. The reaction was stirred overnight. Saturated ammonium chloride solution was added, followed by dilute hydrochloric acid. The organic layer was separated, dried over anhydrous magnesium sulphate and evaporated to give 1-(3,4,5-trichlorophenyl)ethanol. Nuclear Magnetic Resonance Spectrum (NMR) was as follows; 1.2, 3H, d; 4.2, 1H, s; 4.8, 1H, m; 7.3, 2H, s. |

99% | In an oven dried, nitrogen flushed, 500 mL round-bottomed flask equipped with a pressure equalizing addition funnel, 5-bromo- 1,2,3-trichlorobenzene ( 10.0 g, 38.4 mmol) was dissolved in tetrahydrofuran ( 100 mL), and the resulting solution was cooled in an ice bath under nitrogen. /soPropyl magnesium chloride (2 M solution tetrahydrofuran, 21. 1 mL, 42.3 mmol) was added dropwise with good stirring over 15 minutes via the addition funnel . After 0.5 hours, Lambda/,N-dimethylformamide (3.72 mL, 48.0 mmol) was added to the dark solution with stirring . After an additional 0.5 hours, hydrochloric acid ( 1 N, 100 mL) was added with stirring . The layers were separated, and the organic layer was washed with brine. The combined aqueous layers were extracted with ether, and the combined organics were dried over sodium sulfate, filtered, and concentrated to afford the title compound as a white solid ( 10 : 1 mixture of title compound to 1,2,3-trichlorobenzene, 7.96 g, 99%) : NM R (CDCb) delta 9.91 (s, 1H), 7.88 (s, 2H) ; EIMS m/z 209 ( [M ]+). | |
