Coloring agents may be used and examples of the coloring agents include inorganic pigments (e.g. iron oxide, titanium oxide, Prussian blue); organic dyes such as Alizarine dyes, azo dyes, and metal phthalocyanine dyes; and also trace elements such as salts of iron, manganese, boron, copper, cobalt, molybdenum, and zinc.


Generally, the formulations may contain the active components in a range of 0.1 to 95% by weight, preferably 0.5 to 90% by weight.


The active compounds of the formula (I) may be in form of mixed agents with other active compounds, for example, insecticides, poisonous feeds, sterilizers, Acarina-cides, Ascaris-cides, anti-molding agents, breeding control agents, and herbicides in commercially usable formulations and application forms produced from these formulations. Herein, examples of the insecticides are organic phosphorus agents, carbamate agents, carboxylate chemical agents, chlorohydrocarbon type chemical agents, and insecticidal substance produced by microorganism.


The active compounds of the formula (I) may be in form of mixed agents with synergists and the formulations and the applications of them may be those which are commercially usable and the synergists are compounds which are not active themselves but intensify the function of the active compounds.


The contents of the active compounds of the formula (I) in commercialized application forms can be changed in a wide range.


The concentration of the practical use of the active compounds of the formula (I) may be in a range of 0.0000001 to 100% by weight, preferably 0.00001 to 1% by weight.


The compounds of the formula (I) may be used in common manners adequate to the applications.


The active compounds of the invention have efficient stability to alkali of lime substances in the case of use for hygienically harmful insects and harmful insects to storage products and have excellent sustainable property in wood and soil.


Next, the invention will be described more concretely along with Examples; however it is not intended that the invention be limited to the illustrated examples.







SYNTHESIS EXAMPLE 1






3-amino-N-(2-ethyl-6-methyl-4-heptafluoroisopropylphenyl)benzamide (0.21 g) and triethylamine (0.07 g) were added to THF (30 mL) and 4-trifluoromethylnicotinyl chloride (0.12 g) was added and stirred at room temperature for 2 hours. On completion of the reaction, the solvent was removed by distillation at a reduced pressure and the obtained residue was refined by silica gel column chromatography (n-hexane-ethyl acetate mixed solvent) to obtain an aimed product, 3-[4-(trifluoromethyl)nicotinyl]amino-N-(2-ethyl-6-methyl-4-heptafluoroisopropylphenyl)benzamide (0.26 g).

    • melting point: 176 to 179° C.


SYNTHESIS EXAMPLE 2






3-(2-chlorobenzoyl)aminobenzoyl chloride (0.30 g) was added to a THF solution (10 mL) of 2,6-dimethyl-4-heptafluoroisopropylaniline (0.32 g), pyridine (0.16 mL), and 4-dimethylaminopyridine (0.012 g) at a room temperature. After the reaction mixture was stirred at room temperature for 16 hours, it was poured to water and extracted with ethyl acetate. The organic layer was washed with 2N hydrochloric acid and dried with anhydrous magnesium sulfate. The solvent was removed by distillation at a reduced pressure and the obtained residue was refined by silica gel column chromatography (n-hexane-ethyl acetate mixed solvent) to obtain an aimed product, 3-(2-chlorobenzoyl)amino-N-(2,6-dimethyl-4-heptafluoroisopropylphenyl)benzamide (0.23 g).

    • melting point: 141 to 145° C.


The compounds defined by the formula (I) and obtained by same methods as those of the above-mentioned Synthesis Example 1 or 2 are shown in Table 1. The compounds obtained by the Synthesis Examples 1 and 2 are also shown in Table 1.

SYNTHESIS EXAMPLE 3
Raw Material/Intermediate






o-Chlorobenzoyl chloride (3.34 g) was added to THF (10 mL) solution containing ethyl m-aminobenzoate (3.00 g) and pyridine (2.16 g) in ice cooling condition. After the reaction mixture was stirred for 1 hour in ice cooling condition, it was poured to water and extraction was carried out with ethyl acetate. The organic layer was washed with water and dried by anhydrous magnesium sulfate. After the solvent was removed by distillation, the obtained coarse product was washed with a mixed solvent of hexane and tert-butyl methyl ether to obtain an aimed compound, 3-(2-chlorobenzoyl)aminobenzoic acid ethyl ether (5.00 g).

SYNTHESIS EXAMPLE 4
Raw Material/Intermediate






A mixture of 3-(2-chlorobenzoyl)aminobenzoic acid ethyl ether (4.00 g), potassium hydroxide (water 4.7 mL), and ethanol (20 mL) was stirred at room temperature for 4 hours. The reaction mixture was diluted with water and made acidic with 2N hydrochloric acid and the precipitated coarse product was washed with water and dried to obtain 3-(2-chlorobenzoyl)aminobenzoic acid (3.04 g).



1H NMR (300 MHz, DMSO-d6) δ 13.0 (1H, br, s), 10.7 (1H, s), 8.40 (1H, s), 7.90 (1H, d, J=7.8 Hz), 7.70 (1H, d, J=7.8 Hz), 7.42-7.64 (5H, m).


SYNTHESIS EXAMPLE 5
Raw material/Intermediate






One drop of DMF was added to a 1,2-dichloroethane solution containing 3-(2-chlorobenzoyl)aminobenzoic acid (3.52 g) and further thionyl chloride (1.86 mL) was added and the mixture was heated and refluxed for 6 hours. After the solvent was removed by distillation, the coarse product, 3-(2-chlorobenzoyl)aminobenzoyl chloride, was used for the next step without refining treatment.
