Versuchsvorschrift

A mixture composed of 42.7 g (0.1 mol) of 1,4-dihydroxy-2-(N-hexadecylcarbamoyl)naphthalene, 50.1 g (0.3 mol) of 2-(p-nitrophenyl)ethanol, 19 g of p-toluenesulfonic acid and 600 ml of toluene was refluxed by heating for 5 hours and the resulting water was removed by azeotropic distillation. After allowing to cool, toluene was distilled from the reaction mixture under a reduced pressure and the residue was dissolved in ethyl acetate. After washing with water, the thyl acetate was distilled off under a reduced pressure to concentrate and the residue was purified by a silica gel chromatography to obtain 28.2 g of 2-(N-hexadecylcarbamoyl)-4-[2-(p-nitrophenyl)ethoxy]-1-naphthol.
