1-(2-chloro-6-fluorophenyl)ethanol

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 1-(2-Chloro-6-fluorophenyl)ethanol (8.5 g), imidazole (8.1 g) and t-butyldimethylsilylchloride (8.71 g) were stirred in DMF for 24 hours. The mixture was diluted with ether and washed with water, dried (anhydrous magnesium sulphate) and filtered. The filtrate was evaporated to dryness to give 1-(2-chloro-6-fluorophenyl)ethyl (t-butyldimethylsilyi)ether (13.3 g) as a clear oil, NMR (CDCl3) -0.1(s,3H), 0.05(s,3H), 0.85(s,9H), 1.5(d,3H), 5.4(q, 1H), 6.9(m, 1H), 7.05(m,2H). washed with water dried (anhydrous magnesium sulphate) filtered The filtrate was evaporated to dryness

実験手順: 2-chloro-6-fluoro-alpha-methylbenzyl alcohol of (B) (45.1 g, 0.26 mol) is dissolved in chloroform (70 ml), and thionyl chloride (61.5 g, 0.52 mol) is added over a period of 30 minutes. The resultant mixture is refluxed for 16 hours. Excess thionyl chloroform are then removed on a rotary evaporator, resulting in pure title product (46.2 g, 92.6%). Excess thionyl chloroform are then removed on a rotary evaporator

実験手順: 2-chloro-6-fluoroacetophenone of (A) (45.0 g, 0.26 mol) is dissolved in isopropyl alcohol (98 ml) and NaBH4 (4.9 g, 0.13 mol) is added. The resultant mixture is warmed to 55° C. for about 16 hours. A solution of NaOH 10.4 g, 0.26 mol) in water (41. ml) is then added. After 1 hour at 55° C., this reaction mixture is cooled and acidified with diluted HCl. Extraction with chloroform provided pure title product (45.1 g, 99.1%). this reaction mixture is cooled Extraction with chloroform provided pure title product (45.1 g, 99.1%)
