Procedure

In 200 ml of dimethylsulfoxide are dissolved 23 g of 4-nitrochlorobenzene and 25 g of 2,2-dimethyl-2-phenylethylalcohol. To this solution is added 4 g of sodium hydride is added with stirring. After 24 hours stirring at room temperature and another 30 minutes stirring at 60° C, 500 ml of water is added and the mixture is extracted with ether. The extract is washed with water, dried and the solvent is evaporated. Recrystallization of the residue from 200 ml of methanol, gives 28.5 g of 4-(2,2-dimethyl-2-phenylethyloxy)nitrobenzene, melting point: 79°-80° C.
