To a solution of 2 g. of sodium in 50 ml. of methanol at about 0° is added about 35 g. of p-nitrophenyl mercaptan. After about 0.5 hour, about 15 g. of 3,7-dimethyloct-6-enyl bromide is added and then the mixture refluxed for about 3 hours. Then the solvent is evaporated and the concentrate taken up in petroleum ether which is washed with water, dried over magnesium sulfate and evaporated to yield 3,7-dimethyloct-6-enyl p-nitrophenyl sulfide which is used as the starting material in the process of Example 2 to yield 7-ethoxy-3,7-dimethyloctyl p-nitrophenyl sulfide.
