2-{(3-Nitrophenyl)methoxy}ethanol (6.50 g), 1,6-dibromohexane (24.2 g) and tetrabutylammonium bromide (0.21 g) were stirred under nitrogen at 20° and treated with 50% w/v sodium hydroxide (10 ml). The mixture was stirred vigorously for 19 h before water (150 ml) was added. The product was extracted with dichloromethane (3×80 ml) and the combined organic layer was dried (Na2SO4). Solvent evaporation in vacuo gave a residue that was purified by Biotage. Elution with PE-EtOAc (1:0 then 3:1) followed by solvent evaporation in vacuo gave the title compound (8.12 g). HPLC RT=3.238 min.
