Procedure

One gram of 3-isopropylaniline and 0.8 gram of triethylamine were dissolved in 50 ml of THF, cooled to 0° C. and agitated. A solution prepared by dissolving 1.54 grams of 2-trifluoromethylbenzoyl chloride in 20 ml of THF were dropwisely added. After agitating for 30 minutes, the reaction mixture was filtered and THF in the filtrate was distilled off under reduced pressure. The residue was extracted by benzene, and rinsed with 3N-HCl, a saturated sodium bicarbonate solution and water successively in this order. The benzene layer was dried by adding anhydrous magnesium sulfate and then benzene was distilled off under reduced pressure to obtain the desired product. The yield was 1.98 grams (87%), and the product had a melting point of 87.5° to 88.5° C. and an IR absorption peak at 1655 cm-1 (c=b 0).
