Procedure
98.66 g (0.72 mol) of 1-bromo-2-methylpropane, 74.63 g (0.54 mol) of potassium carbonate and 250 ml of dimethylformamide are added to 50 g (0.36 mol) of 4-nitrophenol. The mixture is heated to 100° C. for 4 hours and then evaporated to dryness. The residue is taken up with 500 ml of 1N sodium hydroxide solution, and 200 ml of ether are added. The organic phase is recovered and washed successively three times with 100 ml of 1N sodium hydroxide, then three times with 200 ml of water and finally with 100 ml of saturated sodium chloride solution. It is dried over magnesium sulphate and evaporated to dryness.
