[Industrial Application Field] The present invention relates to a fluoroalkylthioaniline derivative and a method for producing the same. More specifically, the present invention relates to a fluoroalkylthioaniline derivative represented by the following formula (). That is, general formula: In the formula, A represents a group selected from the group consisting of a halogen atom, a lower alkyl group, and a lower alkoxy group, and when multiple A's are present, they may be the same or different; R is represents a fluoro-substituted lower alkyl group, and m represents 0, 1, 2, 3 or 4, provided that m represents 1 and A is at the 3 or 5 position in the benzene ring in the above formula; At, and-
When SCH 2 -R is at the 4 position, A represents a lower alkyl group, m is 2, A is at the 3 and 5 positions of the benzene ring in the above formula, and - The fluoroalkylthioaniline derivative of the above general formula (), in which when SCH 2 -R is at the 4-position, at least one A represents a lower alkoxy group, can be produced, for example, by the following method, and the present invention also relates to the manufacturing method. Manufacturing method General formula In the formula, A and m are the same as above, and M represents a hydrogen atom or an alkali metal atom, and a compound represented by the general formula: A method for producing a fluoroalkylthioaniline derivative of the general formula (), characterized in that R is the same as above, and Z represents an aryl group or a lower alkyl group. The fluoroalkylthioaniline derivative of the general formula () of the present invention is a novel compound that has not been described in any known publications. The compound of general formula () is not only useful as an intermediate for producing insecticidal benzoyl urea derivatives, but also as an intermediate for producing fluoroalkylthioarylisocyanate derivatives, which are intermediates thereof.
It is industrially useful. Therefore, an object of the present invention is to provide a novel fluoroalkylthioaniline derivative useful as an intermediate and a method for producing the same. [Means for Solving the Problems] The compound of general formula () of the present invention can be produced, for example, by the following production method. (In the formula, A, R, m, M and Z are the same as above.) In the above reaction formula, A means that m is 2, 3 or 4.
If there are multiple numbers, they may be the same or different. A is a halogen atom, such as fluoro; chloro; bromo; iodo; a lower alkyl group, such as methyl; ethyl; propyl; isopropyl; n-(iso-, sec- or tert-)butyl, etc., and lower alkyl as exemplified above. can be selected from the group consisting of lower alkoxy groups having groups. Examples of R include the same fluoro-substituted lower alkyl groups as exemplified above. m represents 0, 1, 2, 3 or 4; M represents a hydrogen atom and a member selected from alkali metal atoms such as sodium and potassium; Z represents an aryl group such as a phenyl group or a p-tolyl group; Or it represents the same lower alkyl group as exemplified in A above. In the method for producing a compound of the general formula () of the present invention shown in the above reaction formula, the general formula () which is a raw material is
Specific examples of the compound include 2-mercaptoaniline, 4-mercaptoaniline, and the like. Similarly, specific examples of compounds of general formula () which are raw materials include 2,2,2-trifluoroethyl-p-toluenesulfonate, 2,2,3,3-tetrafluoropropyl-p
-toluenesulfonate, 2,2,3,3,3-pentafluoropropyl-p-toluenesulfonate, and the like, and in place of the above-mentioned p-toluenesulfonates, corresponding methanesulfonates may be used. and benzenesulfonates. Next, a representative example will be shown and the above manufacturing method will be specifically explained. When carrying out the above method, for example, an aprotic polar solvent is used in the presence of a base such as sodium carbonate, potassium carbonate, sodium hydroxide, potassium hydroxide, sodium hydride, etc., and the desired product can be obtained with high purity and high yield. Examples of such solvents include 1,2-dimethoxyethane, dimethylformamide, dimethylacetamide, dimethylsulfoxide, sulfolane, N-methyl-2-pyrrolidone, and hexamethylphosphoramide. . Among protic polar solvents, tertiary alcohols such as tert-butanol can also be used. The above method can be carried out within a wide temperature range. For example, it can be carried out at a temperature between about 0°C and about 120°C, preferably between about 20°C and about 80°C. Further, although it is preferable to carry out the reaction under normal pressure, it is also possible to operate under increased pressure or reduced pressure. In addition, the compound of general formula () as a raw material in the above production method is halonitrobenzene, for example, 4-chloronitrobenzene.

を第1表に示す。It is preferable to carry out the reaction in the above production method by reacting with sodium hydride without separating [Formula]. The compound of general formula (), which is also a raw material in the above production method, is prepared from sulfonyl chlorides and fluoroalkanols by a known method [Journal of the American Chemical Society,
Vol.86, 4645, (1964), also Vol.75, 5978,
(1953), The Journal of Organic Chemistry,
Vol.35, 3195, (1970). ], but these methods are not satisfactory in terms of yield, complexity of isolation of the target compound, cost, etc. In the present invention, in order to solve these problems, a phase transfer catalyst such as triethylbenzylammonium chloride, tetramethylammonium bromide, etc. is used to transfer sulfonyl chloride, fluoroalkanol, and sodium hydroxide. can be easily obtained with high purity and high yield. EXAMPLES Next, the content of the present invention will be specifically explained with reference to Examples, but the present invention should not be limited thereto. [Example] Example 1 4-mercaptoaniline (12.5 g) was converted into N,N'-
Dissolve in dimethylformamide (80 ml) and add potassium tert-butoxide (12 g) under nitrogen atmosphere. 2,2,2-trifluoroethylbenzenesulfonate (23 g) was added dropwise at 20-30°C.
After completion of the dropwise addition, stirring was continued at 30-40°C for 1 hour and at 80-90°C for 5 hours to complete the reaction. After distilling off the low boilers and solvent under reduced pressure, water (200 ml) was added and stirred. The resulting oily substance is extracted with toluene (200 ml), washed successively with 5% aqueous sodium hydroxide solution and water, and dried over anhydrous sodium sulfate. When the residue obtained by distilling off toluene is distilled under reduced pressure, the desired 4-(2,2,2
-trifluoroethylthio)aniline (16.9g)
is obtained. bp.100~105℃/0.8mmHg Compounds synthesized by the same method as in Example 1 are shown in Table 1.

Trifluoroethyl-p-toluenesulfonate can be synthesized according to Reference Example 1 below. Reference example 1 2,2,2-trifluoroethanol (105
g), toluene (200 ml), p-toluenesulfonyl chloride (190.5 g) and triethylbenzylammonium chloride (2.5 g) at 20-35°C from sodium hydroxide (42 g) and water (100 g). Drop an aqueous solution of 50~60℃
After stirring for 4 hours, toluene (800 ml) was added and left to stand. The separated organic layer is washed with water, dried over anhydrous sodium sulfate, and low-boiling substances are distilled off under reduced pressure. Add n-hexane (600 ml) to the residue, cool with ice while stirring vigorously, and the desired 2,2,2-trifluoroethyl-p crystals form.
-Toluenesulfonate (250 g) is obtained.
