反応手順
A solution of 0.6 mole of 2-chlorotrifluoromethylbenzene in 1 l of tetrahydrofuran is cooled to -65° C. and 0.58 mole of butyllithium dissolved in hexane is added. The mixture is maintained at the same temperature for 2 hours and a mixture containing 44 ml of dimethylformamide and 200 ml of tetrahydrofuran is then added dropwise. The reaction medium is allowed to return to ambient temperature, 600 ml of water are added, extraction is then carried out with ethyl ether followed by evaporation to dryness. The product is distilled to purify.
