Komponenten

Versuchsvorschrift

A 25 ml-flask was charged with 0.637 g of hydroquinone, 1 g of optically active 1-bromo-6-methyloctane, 0.667 g of anhydrous potassium carbonate and 4 ml of N,N-dimethylformamide, and reaction was carried out at 90° C. for 9.5 hours. After the reaction, insoluble substances were recovered by filtration and extracted with ether. The ether layer was washed with water and a saturated aqueous solution of sodium chloride and dried, and ether was removed by distillation under reduced pressure. The obtained crude product was purified by silica gel chromatography to obtain 0.32 g of optically active 4-(6'-methyloctyloxy)phenol.
