Versuchsvorschrift

The sodium salt of 4-nitrophenol (28.19 g, 0.175 mol) was dissolved in water (50 mL) and toluene (300 mL) and tetrabutylammonium sulfate (6.0 g) was added. 1,2-Epoxydecane (27.3 g, 0.175 mol) was added to this mixture and the reaction was heated at 100° C. for 5 days. The toluene layer was separated and washed with water (4×75 mL), 1N hydrochloric acid (2×75 mL) and water (75 mL). The organic layer was dried over sodium sulfate, filtered and the solvent removed. The crude product was purified by silica gel chromatography (2–3% methanol/methylene chloride) to afford 4-(2-hydroxy-1-decyloxy)nitrobenzene as a pale oil (20 g, 0.68 mol, 39% yield).
