実験手順: 2-[4-Fluorophenyl]ethanol (7.0 g) was added slowly to a stirred suspension of sodium hydride (1.25 g, 60% as dispersion in oil prewashed with petroleum ether bp 60°-80°) in DMF (50 ml). The mixture was stirred for 30 min at room temperature. Allyl bromide (6.0 g) was then added slowly and the whole allowed to stir overnight. The reaction was partitioned between water and ether. The aqueous layer was further extracted with ether and the combined ethereal extracts were washed with water and dried (MgSO4). The ether was removed under reduced pressure to yield the crude subtitled compound as a colourless oil (8.7 g, 96%). to stir overnight The reaction was partitioned between water and ether The aqueous layer was further extracted with ether the combined ethereal extracts were washed with water dried (MgSO4) The ether was removed under reduced pressure

実験手順: 4-Fluorobenzeneethanol (10.0 g), 1,5-dibromopentane (29 ml), tetra-n-butylammonium hydrogen sulphate (3.2 g, 9 mmol), and aqueous 12.5M NaOH (109 ml) were stirred vigorously at RT overnight. The mixture was diluted with H2O (400 ml), extracted with ER (3×200 ml), and the combined organic extracts were evaporated. The residual oil was purified by [FCS] eluting with CX - ER (100:0→100:6), to give the title compound as a colourless oil (14.37 g). T.l.c.
