4-(3,3,3-trifluoropropyl)propiophenone (hereinafter referred to as compound) of the present invention, which is a (3,3,3-trifluoropropyl)benzene derivative represented by [Formula]) and α-[4-(3,3,3-trifluoropropyl)phenyl]propionic acid (hereinafter referred to as compound) can be synthesized by the following manufacturing method. That is, the compound is synthesized by using 3,3,3-trifluoropropylbenzene as a starting material, reacting it with propionic acid chloride to obtain a compound, and then reacting the compound with methanol in the presence of thallium nitrate. It is possible. Each reaction will be explained in detail below. Synthesis of the compound: The compound is synthesized as shown in the reaction formula below (3,
It can be synthesized by reacting 3,3-trifluoropropyl)benzene and propionic acid chloride in the presence of anhydrous aluminum chloride. The reaction formula is shown below. An example of a reaction process is shown. Anhydrous aluminum chloride is suspended in carbon disulfide, and propionic acid chloride is added dropwise to this suspension at a temperature of 0 to 5°C, while maintaining the reaction temperature at 0 to 10°C (3,3,3-trifluoropropyl ) Add benzene dropwise. After the addition is complete, continue stirring until the generation of hydrogen chloride stops. After the reaction is complete, the reaction mixture is poured into dilute hydrochloric acid over ice to separate the carbon disulfide layer, the separated carbon disulfide solution is washed and dried, and the carbon disulfide is distilled off to remove the reaction mixture. obtain. The obtained reaction mixture was distilled to obtain a (3,3,3-trifluoropropyl)propiophenone fraction, and this fraction was recrystallized from hexane to obtain 4-(3,3,
3-trifluoropropyl)propiophenone is obtained. In this reaction, it is preferable to use anhydrous aluminum chloride in an equimolar amount to the propionic acid chloride to be reacted, and carbon disulfide (3,3,
1 for 3-trifluoropropyl)benzene
It is preferable to use ~10 times (capacity ratio). Synthesis of compounds: Compounds are produced by using the compound as a raw material and reacting it with methanol and thallium () to perform oxidative transformation to obtain the methyl ester of the compound, and then hydrolyzing the obtained methyl ester. Can be done. The reaction formula is shown below. Incidentally, ECTaylor et al. J. Am. Chem. Soc., 95 ,
3340 ('73), reported on the synthesis of α-phenylpropionic acid methyl ester by oxidative rearrangement of propiophenone. In addition, Hamashima reported in Journal of the Society of Organic Synthetic Chemistry 36 , 875 (1978) that α-(4-
We report on the synthesis of isobutyl)phenylpropionate methyl ester. The reaction formula is shown below. The present inventors have discovered that methyl esters of compounds can be easily produced by applying Hamashima's reaction conditions to the compounds, and have thus arrived at the present invention. The method for synthesizing a compound from compounds consists of the following three steps. (1) Preparation of thallium () catalyst: Dissolve thallium nitrate in a mixture of methyl orthoformate and methanol, and add silica gel (Wako Gel C-200) to this solution. The solvent is distilled off from this mixture under reduced pressure, and the mixture is dried to obtain silica gel supporting thallium and methanol. (2) Oxidative rearrangement: An oxidative rearrangement reaction can be carried out by adding the catalyst and compound obtained in (1) above to carbon tetrachloride and reacting at 70°C for 1 to 10 hours. Upon completion of the reaction, the solid matter is separated and the solvent is distilled off from the resulting liquid to obtain a reaction mixture. The resulting reaction mixture consists of the methyl ester of the compound, the compound and by-products, and is subjected to subsequent hydrolysis either as a mixture or after isolation of the methyl ester. (3) Hydrolysis: A hydrolysis reaction can be carried out by adding ethanol and caustic soda to the reaction mixture obtained in (2) above or the isolated methyl ester and heating under reflux conditions for 1 to 3 hours. After the reaction is complete, the solvent is distilled off, water is added, the aqueous layer is washed with ether, and then the aqueous layer is acidified with dilute hydrochloric acid to precipitate the compound. A compound is obtained by extracting this with ether and distilling off the ether. The compounds are useful as anti-inflammatory agents. For example, the conventional carrageenin edema test (CAWinter, Proc.
Soc.Exp.Biol.Med., 111 , 544 ('64)) in rats, oral administration of 200 mg/Kg resulted in a
It showed a 50% edema suppression rate. The compounds of the present invention are also useful as intermediates for organic synthesis. The present invention will be explained in more detail below based on examples. However, the present invention is not limited to the following examples. Example 1 Capacity 2 equipped with stirrer and dropping funnel
Pour 500ml of carbon disulfide into a round bottom flask, and add 110g of anhydrous aluminum chloride while stirring.
(0.825M) and suspended. 76.3 g (0.825 M) of propionic acid chloride was added dropwise over 50 minutes while cooling the flask from the outside so that the internal temperature of the flask was 0 to 5°C. Next, 130.5 g (0.75 M) of (3,3,3-trifluoropropyl)benzene was added dropwise so that the internal temperature was 0 to 5°C. After the addition was completed, stirring was continued for 5 hours, and the generation of hydrogen chloride had almost stopped, so the contents were poured into dilute hydrochloric acid covered with ice, and then the carbon disulfide layer was separated.
The separated carbon disulfide layer was washed with water, a 10% aqueous sodium carbonate solution, and then water, dried over calcium chloride, and the carbon disulfide was distilled off to give 159.3 g of the reaction mixture.
I got it. The resulting reaction mixture was distilled to a boiling point of 100
90.5g of a fraction at ~104℃/1.8mmHg was obtained, and this fraction was further recrystallized with n-hexane to obtain a crystalline compound.
72.5g was obtained. The product purified by recrystallization was found to be 4-(3,3,3-trifluoropropyl)propiophenone from the following analysis results.

140g was added, but the temperature of the liquid at this point rose to 32°C. After stirring for 10 minutes, the solvent was distilled off and the
It was dried for 2 hours at mmHg and 50°C to obtain 195 g of white powder. Next, an oxidative rearrangement reaction of the compound was carried out as follows. In a 2 volume round bottom flask equipped with a stirrer and a reflux condenser was added 196 g of the above thallium reagent white powder, 900 ml of carbon tetrachloride, and compound 30.
