Procedure

A mixture of 75 g of 4-nitrophenol, 149.5 g of 1-bromotetradecane, 26.96 g of sodium hydroxide, 2.18 g of trioctyl methylammonium chloride, 400 ml of toluene and 400 of water is heated at reflux for 65 hours. The organic layer is separated, washed with 1N sodium hydroxide and dilute hydrochloric acid, dried and concentrated in vacuo. The residue is recrystallized from petroleum ether to give the desired product.
