To a solution of p-nitrophenol (2 g.) in dimethylformamide (10 ml.) is added anhydrous potassium carbonate (2 g.) and 3,7-dimethylocta-2,6-dienyl bromide (3.1 g.). The reaction is kept at 50° for 12 hours, diluted with water and extracted with ether. The ethereal extract is washed with 5% aqueous sodium hydroxide and dried over sodium sulfate. The crude product is purified by distillation to yield 3,7-dimethylocta-2,6-dienyl p-nitrophenyl ether.
