Isobutylene gas was passed into a solution of 17.4 parts by weight of 3-(2'-chloro-4'-trifluoromethylphenoxy)-6-nitrobenzyl alcohol in 100 parts by volume of 1,2-dichloroethane and 0.5 parts by weight of sulfuric acid at 40° C. for two hours. The reaction mixture was then washed with dilute aqueous sodium bicarbonate solution and twice with water, and the organic phase was dried with magnesium sulfate, filtered and concentrated. 18 parts by weight (89% of theory) of 3-(2'-chloro-4'-trifluoromethylphenoxy)-6-nitrobenzyl tert.-butyl ether (compound No. 16) of melting point 75°-78° C. were obtained.
