実験手順
To a solution of 20.0 g of p-prenylacetophenone in 200 ml of methanol, 1.5 g of sodium borohydride was added at 20° C. with stirring. After stirring for 4 hours, 300 ml of water was added, the resulting solution was extracted with ethyl ether. The extract was washed with water, dried, concentrated and distilled to give 18.5 g of 1-(p-prenylphenyl)-ethanol, b.p. 107-108 °C/0.30 mmHg.
