実験手順

73 parts by weight of potassium 3-cresolate, 107 parts by weight of 3,4-dichlorobenzotrifluoride and 6.9 parts by weight of potassium carbonate in 500 parts by volume of dimethylsulfoxide were stirred at 140° C. for 8 hours. The reaction mixture was cooled to room temperature and was poured into 2,000 parts by volume of water. The oily residue was taken up in ether, and the organic phase was dried with magnesium sulfate, filtered, and concentrated under reduced pressure. Fractional distillation gave 120 parts by weight (84% of theory) of 3-(2'-chloro-4'-trifluoromethylphenoxy)-toluene of boiling point 91°-96° C./0.1 bar and refractive index nD25 : 1.5268.
