  • Figure US20220000112A1-20220106-C00005
  • Firstly, in the present invention, the term “unsubstituted” indicates a group including only a mother nucleus. When a group is referred to as a name of a mother nucleus without “substituted”, this refers to “unsubstituted” unless specifically indicated otherwise.
  • On the other hand, the term “substituted” indicates that at least one of the hydrogen atoms of the mother nucleus is substituted with a substituent having a structure that is the same as the structure of the mother nucleus or different from the structure of the mother nucleus. Thus, a “substituent” is another group bonded with the mother nucleus. There may be one substituent or two or more substituents. Two or more substituents may be the same as or different from each other.
  • For example, the term “C1-6” or the like indicates that the number of carbon atoms of the mother nucleus is 1 to 6. The number of carbon atoms present in substituents is not included in this number of carbon atoms. For example, a butyl group having an ethoxy group as a substituent thereof is classified as a C2 alkoxy C4 alkyl group.

  • 0.27 g (0.63 mmol, 1.0 eq) of 2-(2-ethyl sulfanyl-4-(trifluoromethyl)phenyl)-1-methyl-5-(4-(trifluoromethyl)phenyl)-1H-imidazol e was dissolved in 7 ml of chloroform followed by stirring at 0° C. 0.31 g (70%, 1.3 mmol, 2.0 eq) of metachloroperbenzoic acid was added to the resulting solution followed by stirring for 2 hours at 0° C. The resulting reaction liquid was poured to a mixed solution of saturated aqueous solution of sodium hydrogen carbonate and saturated aqueous solution of sodium thiosulfate followed by extracting with chloroform. The obtained organic layer was washed with brine, stirred by adding anhydrous magnesium sulfate and filtered. The filtrate was concentrated under include pressure and the obtained residue was purified by silica gel column chromatography to obtain 0.15 g of the objective compound (yield: 51%).
  • 1H-NMR of the obtained compound is shown below:
  • 1H-NMR (400 MHz, CDCl3): δ 8.47 (m, 1H), 8.03 (m, 1H), 7.73 (m, 3H), 7.60 (m, 2H), 3.47 (q, 2H), 3.44 (s, 3H), 1.26 (t, 3H).
  • TABLE 1 to TABLE 9 show the compounds of the present invention produced by the same production process of the above-described Examples. In addition, the physical properties of the compounds are shown in the column of “Physical Property”. As the physical properties, property, melting point (m.p.) or refraction index are shown.
  • In addition, in the tables, Ph represents phenyl group, Me represents methyl group, Et represents ethyl group, nPr represents normal propyl group, iPr represents isopropyl group, cPr represents cyclopropyl group, nBu represent normal butyl group, sBu represents secondary butyl group and tBu represents tertial butyl group.
  • TABLE 1 shows the substituents of the compounds represented by formula (1).

    • (Test Example 11) Efficacy Test Against Pseudaletia Separate (Seed Treatment Test)
  • 0.1 g of each compound of the present invention was diluted with 2 ml of acetone to prepare a chemical solutions for test. 10 g of wheat seeds was added to the chemical solution for test and air dried, followed by seedling 100 seeds in a planter. After keeping the planter in a warm room with a temperature of 25° C. for 7 days, 100 first-instar larvae of Pseudaletia separate were released in the planter. The planter was kept in a war room with a temperature of 25° C., the number of living Pseudaletia separate was investigated after 3 days were passed, and the prevention rate was calculated by the following equation. The test was repeated twice.

  • Prevention rate=[1−(Nt)/(Nc)]×100
  • Nt: number of parasites in spray-treatment area
  • Nc: number of parasites in control area
  • The efficacy test against the first-instar larvae of Pseudaletia separate was carried out for Compounds 1-47, 1-65, 1-69, 1-102, 2-5 and 6-53. As a result, all of the compounds demonstrated 80% or more of prevention rate against the first-instar larvae of Pseudaletia separate.
