[1314]

[1315] 10 g of 1,2-phenylenediamine, 32.7 g of heptafluoro-2-iodopropane, 14.6 g of sodium carbonate and 1 g of tetrabutylammonium hydrogen sulfate were sequentially added to a mixed solution of 100 ml of ethyl acetate and 100 ml of water. Under stirring at room temperature, 16 g of sodium dithionite was added in small amounts over 30 minutes. After the addition, the temperature was raised to 40°C and stirred for 1 hour. After separating the organic layer, it was washed with saturated brine, and dried over magnesium sulfate. The solvent was distilled off under reduced pressure to obtain 24.3 g of 4-heptafluoroisopropyl-1,2-phenylenediamine.

[1320] 2.76 g of 4-heptafluoroisopropyl-1,2-phenylenediamine was dissolved in 5 ml of trifluoroacetic acid, and the reaction was carried out under heating and reflux for 3 hours. After the reaction, the excess trifluoroacetic acid was distilled off under reduced pressure, and the obtained residue was washed with an ether-hexane mixed solvent to obtain 5-heptafluoroisopropyl-2-trifluoromethyl-1H-benzo Imidazole 3.1g.

Description

Technical field [0001] The present invention relates to a pesticide for agriculture and horticulture using a novel phthalamide derivative containing a condensed heterocyclic group or a salt thereof as an active ingredient and a method of use thereof. Background technique [0002] So far, although various pesticides for agriculture and horticulture have been developed, the damage caused by pests in the production of crops such as agriculture and horticulture is still serious. In addition, there are pests that are resistant to conventional pesticides. Therefore, it is desired to develop a new pesticide for agriculture and horticulture. In addition, various labor-saving application methods are sought due to the aging of agricultural workers, and the development of agricultural and horticultural pesticides having characteristics suitable for these application methods has also been sought. [0003] Patent Documents 1, 2, 3, and 4 describe the use of certain phthalamide derivatives as i...
