Description
TECHNICAL FIELD

The present invention relates to a herbicide containing a substituted thienopyrimidine derivative as an active ingredient, a method of using the same, a novel compound useful as the herbicide and a process for producing the same, and an intermediate thereof.


BACKGROUND OF THE INVENTION

It is indispensable to supply important crops stably for solving the food crisis caused by world population growth that is expected to come near future. For stable supply of the crops, it is necessary to kill or control weeds harmful at cultivation and harvest of the crops economically and efficiently. Therefore, it is increasingly important to develop a novel herbicide or plant growth regulator which can offer a solution.


On the other hand, most of the reports on substituted thienopyrimidines are those on physiological activities thereof in pharmaceutical application and no description thereof as herbicides have not been found in the reports (for example, cf. WO98/50037, WO96/14319, EP-150469-A1, DE-2323149 and WO02/55524).


DISCLOSURE OF THE INVENTION

In order to respond to such a social request, an object of the present invention is to provide a novel herbicide having a high safety for crops and also an excellent herbicidal activity against weeds.


As a result of intensive studies for solving the above-described problem, inventors of the present invention have found that a thienopyrimidine having a specific substituent exhibit a herbicidal activity, and have accomplished the invention.

embedded image


A mixed solution of ethanol (100 mL) and triethylamine (28.0 g, 0.277 mol) was cooled with ice-water and then 3-(trifluoromethoxy)benzoyl chloride (50.0 g, 0.223 mol) was slowly added dropwise thereto, followed by stirring at room temperature for 3 hours. After completion of the reaction, the solvent was removed by evaporation and the resulting residue was dissolved in ethyl acetate. After the solution was washed with water and saturated brine, the solvent was removed by evaporation. The resulting residue was purified on a silica gel column (Kiesel gel 60 manufactured by MERCK, 2% AcOEt-Hex) to obtain ethyl 3-(trifluoromethoxy)benzoate (52.0 g, 99%).

An ammonia gas was bubbled into a four-neck flask cooled in a dry ice-acetone bath to collect liquid ammonia (87 g). Thereto was added sodium amide (8.26 g, 0.212 mol) and then were added a toluene solution (10 mL) of acetonitrile (8.69 g, 0.212 mol) and a toluene solution (10 mL) of ethyl 4-fluoro-3-(trifluoromethyl)benzoate (25.0 g, 0.106 mol), followed by stirring at −70° C. for 1 hour. While the reaction liquid was warmed to room temperature, the ammonia gas was released outside the system. After completion of the reaction, the reaction liquid was poured into water and extracted with toluene. The resulting aqueous layer from which insoluble matter had been removed was acidified with concentrated hydrochloric acid, followed by extraction with ethyl acetate. After the resulting extract was washed with water and saturated brine, the solvent was removed by evaporation.

While the gas generation state was taken into account, acetonitrile (3.65 g, 89.0 mmol) was slowly added dropwise thereto, followed by continuation of heating under stirring at 85° C. for 2 hours. After completion of the reaction, the reaction liquid was poured into water, followed by extraction with toluene. Thereafter, the resulting aqueous layer was cooled with ice water and acidified with concentrated hydrochloric acid. After filtration of precipitated crystals, the resulting crystals were washed with water and hexane and dried to obtain 3-oxo-3-[3-(trifluoromethyl)phenyl]propionitrile (8.17 g, 80%).

FORMULATION EXAMPLE 2
Emulsifiable Concentrate

Ten parts of each of the compounds shown in Tables 1 to 6 were dissolved in a mixed solvent of 40 parts of an aromatic hydrocarbon type solvent Solvesso 200 (trademark, Exxon Chemical Co.) and 40 parts of N,N-dimethylacetamide.

The resulting ground material were kneaded with 20 parts of water. Thereafter, the blend was extruded from an extrusion granulator through nozzles having a diameter of 0.6 mm, dried at 60° C. for 2 hours, and then chopped to a length of 1 to 2 mm to obtain granules containing 1% of the active ingredient.


Test Examples of the herbicides of the present invention are shown below.


TEST EXAMPLE 1
Field Foliar Treatment Test

Alluvial soil from a field was put in a resin-made vat having an area of 200 cm2. After fertilization, the seeds of Echinochloa crus-galli, Brassica juncea, and Ipomoea purpurea were cast on the soil and uniformly covered with the soil. Then, cultivation was continued in a greenhouse, and when the weeds to be tested reached the 1.0- to 2.0-leaf stage, the wettable powder obtained in Formulation Example 1 was diluted with water and a predetermined amount thereof was sprayed uniformly to the weeds by means of a small-sized power pressure spray to give 10 g of the active ingredient per an are. Thereafter, cultivation was further continued in the greenhouse, and the herbicidal effect was examined on the 21st day from the treatment. The results obtained are shown in Table 7 (the compound numbers in Table 7 correspond to those in Table 1 to 6).


The herbicidal effect was evaluated in terms of herbicidal rate obtained from the following equation:

Herbicidal rate (%)=[1−(Weight of weeds above the ground in a treated plot)/(Weight of weeds above the ground in a non-treated plot)]×100


and was expressed by herbicidal index according to the following criteria.
