25.1 g of 1-p-ethylphenyl-2-nitro-1-hexanol and 14.6 g of ethoxybenzene are dissolved in 80 ml of methylene chloride, and the solution is added dropwise at 0° C, with vigorous stirring, to 90 g of conc. sulphuric acid and 10 ml of water. After 2 hours' stirring at room temperature, the mixture is poured on to 400 ml of ice water. The product is taken up in methylene chloride and washed with saturated sodium bicarbonate solution. After the solvent has been removed by evaporation, the oil remaining behind is dried in high vacuum at 60° C for 2 hours. There is obtained the compound of the formula ##STR7## as viscous, dark yellow oil having a refractive index of nD22 = 1.5452.
