The compounds of the formulae I or II can be prepared by the standard methods of organic chemistry, e.g. by the methods described hereinafter or in the working examples:
The compounds of the formula I, wherein X1 is O and X3 is a lone pair, can be prepared e.g. according to the method depicted in scheme 1 by reacting activated pyrazole carboxylic acid derivative II with a 3-aminopyridine compound III (see e.g. Houben-Weyl: “Methoden der organ. Chemie” [Methods of Organic Chemistry], Georg-Thieme-Verlag, Stuttgart, N.Y. 1985, Volume E5, pp. 941-1045). Activated pyrazole carboxylic acid derivatives II are, for example, halides, activated esters, anhydrides, azides, for example chlorides, fluorides, bromides, para-nitrophenyl esters, pentafluorophenyl esters, N-hydroxysuccinimides, hydroxybenzotriazol-1-yl esters. In scheme 1, the radicals A, R1, R2 and R3 have the meanings mentioned above and in particular the meanings mentioned as being preferred, X is a suitable leaving group such as halogen, N3, paranitrophenoxy or pentafluorophenoxy etc.
The active compounds of the formula I, wherein X1 is O and X3 is a lone pair, can also be prepared, for example, by reacting the pyrazole carboxylic acid IV with a 3-aminopyridine compound III in the presence of a coupling agent according to scheme 2. In scheme 2, the radicals A, R1, R2 and R3 have the meanings given above and in particular the meanings given as being preferred.
Suitable coupling agents are, for example:
Compounds I where X1 is O, X3 is a lone pair and R1 is different from hydrogen can also be prepared by alkylating the amides I (in which R1 is hydrogen and which can be obtained according to scheme 1 or 2) using suitable alkylating agents in the presence of bases.
The pyrazole carboxylic acids IV and their activated derivatives II as well as 3-aminopyridine compounda III are known in the art or are commercially available or can be prepared by methods known from the literature.
Compounds of the formula I, wherein X1 is different from oxygen, can be prepared from the compounds Ia by standard methods:
Compounds of the formula I, wherein X1 is S, can be prepared e.g. by reacting a compound Ia with 2,4-bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4-disulfide or phorphorus pentasulfide according to the method described by M. Jesberger et al. in Synthesis 2003, 1929.
Compounds of the formula I, wherein X1 is NR1a, can be prepared e.g. by reacting a compound Ia with by reacting a compound Ia with 2,4-bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4-disulfide to obtain the corresponding thioamide (compound I, wherein X1 is S) which is then reacted with an appropriate amine according to the method described by V. Glushkov et al. in Pharmaceutical Chemistry Journal 2005, 39(10), 533-536.
Compounds of the formula II, wherein X2═SR2a, can be prepared by alkylation of the corresponding thioamide (compound I, wherein X1 is S) by reaction with an alkylating agent according to the method described by V. Glushkov et al. in Pharmaceutical Chemistry Journal 2005, 39(10), 533-536. In a similar manner, compounds I, wherein X2 is OR2a or NR2bR2c can be obtained. Compounds of the formula II, wherein X2═SOR2a or SO2R2a can be obtained by oxidation of compounds II with X2═SR2a.
Compounds of the formulae I and II, wherein X3 is O, can be prepared by oxidation of compounds I, wherein X3 is a lone pair, according to standard methods of preparing pyridine N-oxides, e.g. by the method described C. Botteghi et al. in Journal of Organometallic Chemistry 1989, 370, 17-31.
As a rule, the compounds of the formulae I or II can be prepared by the methods described above. If individual compounds cannot be prepared via the above-described routes, they can be prepared by derivatization of other compounds I or II or by customary modifications of the synthesis routes described. For example, in individual cases, certain compounds I or II can advantageously be prepared from other compounds I or II by ester hydrolysis, amidation, esterification, ether cleavage, olefination, reduction, oxidation and the like.
The reaction mixtures are worked up in the customary manner, for example by mixing with water, separating the phases, and, if appropriate, purifying the crude products by chromatography, for example on alumina or on silica gel. Some of the intermediates and end products may be obtained in the form of colorless or pale brown viscous oils which are freed or purified from volatile components under reduced pressure and at moderately elevated temperature. If the intermediates and end products are obtained as solids, they may be purified by recrystallization or trituration.

For seed treatment purposes, respective formulations can be diluted 2-10 fold leading to concentrations in the ready to use preparations of 0.01 to 60% by weight active compound by weight, preferably 0.1 to 40% by weight.
The compounds of formulae I or II can be used as such, in the form of their formulations or the use forms prepared therefrom, for example in the form of directly sprayable solu-tions, powders, suspensions or dispersions, emulsions, oil dispersions, pastes, dusta-ble products, materials for spreading, or granules, by means of spraying, atomizing, dusting, spreading or pouring. The use forms depend entirely on the intended purposes; they are intended to ensure in each case the finest possible distribution of the active compound(s) according to the invention.
Aqueous use forms can be prepared from emulsion concentrates, pastes or wettable powders (sprayable powders, oil dispersions) by adding water. To prepare emulsions, pastes or oil dispersions, the substances, as such or dissolved in an oil or solvent, can be homogenized in water by means of a wetter, tackifier, dispersant or emulsifier. However, it is also possible to prepare concentrates composed of active substance, wetter, tackifier, dispersant or emulsifier and, if appropriate, solvent or oil, and such concentrates are suitable for dilution with water.
The active compound concentrations in the ready-to-use preparations can be varied within relatively wide ranges. In general, they are from 0.0001 to 10%, preferably from 0.01 to 1% per weight.
The active compound(s) may also be used successfully in the ultra-low-volume process (ULV), it being possible to apply formulations comprising over 95% by weight of active compound, or even to apply the active compound without additives.

The compounds of formulae I or II are also suitable for the treatment of plant propagation materials (such as seed). Conventional seed treatment formulations include for example flowable concentrates FS, solutions LS, powders for dry treatment DS, water dispersible powders for slurry treatment WS, water-soluble powders SS and emulsion ES and EC and gel formulation GF. These formulations can be applied to the seed diluted or undiluted. Application to the seeds is carried out before sowing, either directly on the seeds or after having pregerminated the latter
In a preferred embodiment a FS formulation is used for seed treatment. Typically, a FS formulation may comprise 1-800 g/l of active ingredient, 1-200 g/l Surfactant, 0 to 200 g/l antifreezing agent, 0 to 400 g/l of binder, 0 to 200 g/l of a pigment and up to 1 liter of a solvent, preferably water.
Other preferred FS formulations of compounds of formulae I or II for seed treatment comprise from 0.5 to 80 wt % of the active ingredient, from 0.05 to 5 wt % of a wetter, from 0.5 to 15 wt % of a dispersing agent, from 0.1 to 5 wt % of a thickener, from 5 to 20 wt % of an anti-freeze agent, from 0.1 to 2 wt % of an anti-foam agent, from 1 to 20 wt % of a pigment and/or a dye, from 0 to 15 wt % of a sticker/adhesion agent, from 0 to 75 wt % of a filler/vehicle, and from 0.01 to 1 wt % of a preservative.
Various types of oils, wetters, adjuvants, herbicides, fungicides, other pesticides, or bactericides may be added to the active ingredients, if appropriate just immediately prior to use (tank mix). These agents usually are admixed with the agents according to the invention in a weight ratio of 1:10 to 10:1.
The compounds of formulae I or II are effective through both contact (via soil, glass, wall, bed net, carpet, plant parts or animal parts), and ingestion (bait, or plant part).
For use against ants, termites, wasps, flies, mosquitos, crickets, or cockroaches, compounds of formulae I or II are preferably used in a bait composition.
The bait can be a liquid, a solid or a semisolid preparation (e.g. a gel). Solid baits can be formed into various shapes and forms suitable to the respective application e.g. granules, blocks, sticks, disks. Liquid baits can be filled into various devices to ensure proper application, e.g. open containers, spray devices, droplet sources, or evaporation sources. Gels can be based on aqueous or oily matrices and can be formulated to particular necessities in terms of stickyness, moisture retention or aging characteristics.
The bait employed in the composition is a product, which is sufficiently attractive to incite insects such as ants, termites, wasps, flies, mosquitos, crickets etc. or cockroaches to eat it. The attractiveness can be manipulated by using feeding stimulants or sex pheromones. Food stimulants are chosen, for example, but not exclusively, from animal and/or plant proteins (meat-, fish- or blood meal, insect parts, egg yolk), from fats and oils of animal and/or plant origin, or mono-, oligo- or polyorganosaccharides, especially from sucrose, lactose, fructose, dextrose, glucose, starch, pectin or even molasses or honey. Fresh or decaying parts of fruits, crops, plants, animals, insects or specific parts thereof can also serve as a feeding stimulant. Sex pheromones are known to be more insect specific. Specific pheromones are described in the literature and are known to those skilled in the art.
Formulations of compounds of formulae I or II as aerosols (e.g in spray cans), oil sprays or pump sprays are highly suitable for the non-professional user for controlling pests such as flies, fleas, ticks, mosquitos or cockroaches. Aerosol recipes are preferably com-posed of the active compound, solvents such as lower alcohols (e.g. methanol, etha-nol, propanol, butanol), ketones (e.g. acetone, methyl ethyl ketone), paraffin hydrocar-bons (e.g. kerosenes) having boiling ranges of approximately 50 to 250° C., dimethyl-formamide, N-methylpyrrolidone, dimethyl sulphoxide, aromatic hydrocarbons such as toluene, xylene, water, furthermore auxiliaries such as emulsifiers such as sorbitol monooleate, oleyl ethoxylate having 3-7 mol of ethylene oxide, fatty alcohol ethoxylate, perfume oils such as ethereal oils, esters of medium fatty acids with lower alcohols, aromatic carbonyl compounds, if appropriate stabilizers such as sodium benzoate, am-photeric surfactants, lower epoxides, triethyl orthoformate and, if required, propellants such as propane, butane, nitrogen, compressed air, dimethyl ether, carbon dioxide, nitrous oxide, or mixtures of these gases.
The oil spray formulations differ from the aerosol recipes in that no propellants are used.
The compounds of formulae I or II and their respective compositions can also be used in mosquito and fumigating coils, smoke cartridges, vaporizer plates or long-term vaporizers and also in moth papers, moth pads or other heat-independent vaporizer systems.
Methods to control infectious diseases transmitted by insects (e.g. malaria, dengue and yellow fever, lymphatic filariasis, and leishmaniasis) with compounds of formulae I or II and its respective compositions also comprise treating surfaces of huts and houses, air spraying and impregnation of curtains, tents, clothing items, bed nets, tsetse-fly trap or the like. Insecticidal compositions for application to fibers, fabric, knitgoods, nonwovens, netting material or foils and tarpaulins preferably comprise a mixture including the insecticide, optionally a repellent and at least one binder. Suitable repellents for exam-pie are N,N-diethyl-meta-toluamide (DEET), N,N-diethylphenylacetamide (DEPA), 1-(3-cyclohexan-1-yl-carbonyl)-2-methylpiperine, (2-hydroxymethylcyclohexyl)acetic acid lactone, 2-ethyl-1,3-hexandiol, indalone, Methylneodecanamide (MNDA), a pyrethroid not used for insect control such as {(+/−)-3-allyl-2-methyl-4-oxocyclopent-2-(+)-enyl-(+)-trans-chrysantemate (Esbiothrin), a repellent derived from or identical with plant extracts like limonene, eugenol, (+)-Eucamalol (1), (−)-1-epi-eucamalol or crude plant extracts from plants like Eucalyptus maculata, Vitex rotundifolia, Cymbopogan martinii, Cymbopogan citratus (lemon grass), Cymopogan nartdus (citronella). Suitable binders are selected for example from polymers and copolymers of vinyl esters of aliphatic acids (such as such as vinyl acetate and vinyl versatate), acrylic and methacrylic esters of alcohols, such as butyl acrylate, 2-ethylhexylacrylate, and methyl acrylate, mono- and diethylenically unsaturated hydrocarbons, such as styrene, and aliphatic diens, such as butadiene.
The impregnation of curtains and bednets is done in general by dipping the textile material into emulsions or dispersions of the active compounds of formulae I and II or spraying them onto the nets.
Methods which can be employed for treating the seed are, in principle, all suitable seed treatment and especially seed dressing techniques known in the art, such as seed coating (e.g. seed pelleting), seed dusting and seed imbibition (e.g. seed soaking). Here, “seed treatment” refers to all methods that bring seeds and the compounds of formulae I or II into contact with each other, and “seed dressing” to methods of seed treatment which provide the seeds with an amount of the compounds of formulae I or II, i.e. which generate a seed comprising the compound of formulae I or II. In principle, the treatment can be applied to the seed at any time from the harvest of the seed to the sowing of the seed. The seed can be treated immediately before, or during, the planting of the seed, for example using the “planter's box” method. However, the treatment may also be carried out several weeks or months, for example up to 12 months, before planting the seed, for example in the form of a seed dressing treatment, without a substantially reduced efficacy being observed.
Expediently, the treatment is applied to unsown seed. As used herein, the term “unsown seed” is meant to include seed at any period from the harvest of the seed to the sowing of the seed in the ground for the purpose of germination and growth of the plant.
Specifically, a procedure is followed in the treatment in which the seed is mixed, in a suitable device, for example a mixing device for solid or solid/liquid mixing partners, with the desired amount of seed treatment formulations, either as such or after previous dilution with water, until the composition is distributed uniformly on the seed. If appropriate, this is followed by a drying step.

A further object of the present invention is therefore to provide new methods for controlling parasites in and on animals. Another object of the invention is to provide safer pesticides for animals. Another object of the invention is further to provide pesticides for animals that may be used in lower doses than existing pesticides. And another object of the invention is to provide pesticides for animals, which provide a long residual control of the parasites.
The invention also relates to compositions containing a parasiticidally effective amount of compounds of formulae I or II or the enantiomers or veterinarily acceptable salts thereof and an acceptable carrier, for combating parasites in and on animals.
The present invention also provides a method for treating, controlling, preventing and protecting animals against infestation and infection by parasites, which comprises orally, topically or parenterally administering or applying to the animals a parasiticidally effective amount of a compound of formulae I or II or the enantiomers or veterinarily acceptable salts thereof or a composition comprising it.

The invertebrate pest, i.e. arthropodes and nematodes, the plant, soil or water in which the plant is growing can be contacted with the present compound(s) I or II or composition(s) containing them by any application method known in the art. As such, “contacting” includes both direct contact (applying the compounds/compositions directly on the invertebrate pest or plant—typically to the foliage, stem or roots of the plant) and indirect contact (applying the compounds/compositions to the locus of the invertebrate pest or plant).
Moreover, invertebrate pests may be controlled by contacting the target pest, its food supply, habitat, breeding ground or its locus with a pesticidally effective amount of compounds of formulae I or II. As such, the application may be carried out before or after the infection of the locus, growing crops, or harvested crops by the pest.
“Locus” means a habitat, breeding ground, cultivated plants, plant propagation material (such as seed), soil, area, material or environment in which a pest or parasite is growing or may grow.
In general “pesticidally effective amount” means the amount of active ingredient needed to achieve an observable effect on growth, including the effects of necrosis, death, retardation, prevention, and removal, destruction, or otherwise diminishing the occurrence and activity of the target organism. The pesticidally effective amount can vary for the various compounds/compositions used in the invention. A pesticidally effective amount of the compositions will also vary according to the prevailing conditions such as desired pesticidal effect and duration, weather, target species, locus, mode of application, and the like.
The compounds of formulae I or II and its compositions can be used for protecting wooden materials such as trees, board fences, sleepers, etc. and buildings such as houses, outhouses, factories, but also construction materials, furniture, leathers, fibers, vinyl articles, electric wires and cables etc. from ants and/or termites, and for controlling ants and termites from doing harm to crops or human being (e.g. when the pests invade into houses and public facilities). The compounds of are applied not only to the surrounding soil surface or into the under-floor soil in order to protect wooden materials but it can also be applied to lumbered articles such as surfaces of the under-floor concrete, alcove posts, beams, plywood, furniture, etc., wooden articles such as particle boards, half boards, etc. and vinyl articles such as coated electric wires, vinyl sheets, heat insulating material such as styrene foams, etc. In case of application against ants doing harm to crops or human beings, the ant controller of the present invention is applied to the crops or the surrounding soil, or is directly applied to the nest of ants or the like.
The compounds of formulae I and II can also be applied preventively to places at which occurrence of the pests is expected.
The compounds of formulae I or II may also be used to protect growing plants from attack or infestation by pests by contacting the plant with a pesticidally effective amount of compounds of formula I or II. As such, “contacting” includes both direct contact (applying the compounds/compositions directly on the pest and/or plant—typically to the foliage, stem or roots of the plant) and indirect contact (applying the compounds/compositions to the locus of the pest and/or plant).
In the case of soil treatment or of application to the pests dwelling place or nest, the quantity of active ingredient ranges from 0.0001 to 500 g per 100 m2, preferably from 0.001 to 20 g per 100 m2.
Customary application rates in the protection of materials are, for example, from 0.01 g to 1000 g of active compound per m2 treated material, desirably from 0.1 g to 50 g per m2.
Insecticidal compositions for use in the impregnation of materials typically contain from 0.001 to 95% by weight, preferably from 0.1 to 45% by weight, and more preferably from 1 to 25% by weight of at least one repellent and/or insecticide.

For use in treating crop plants, the rate of application of the active ingredients of this invention may be in the range of 0.1 g to 4000 g per hectare, desirably from 25 g to 600 g per hectare, more desirably from 50 g to 500 g per hectare.
In the treatment of seed, the application rates of the active ingredients are generally from 0.1 g to 10 kg per 100 kg of seed, preferably from 1 g to 5 kg per 100 kg of seed, in particular from 1 g to 200 g per 100 kg of seed.
The present invention is now illustrated in further detail by the following examples.
The procedure described in the following synthesis examples was used to prepare further compounds of the formula I by appropriate modification of the starting material. The resulting compounds, together with physical data, are listed below in tables I and II.
Products were characterized by HPLC (High Performance Liquid Chromatography Mass Spectrometry). HPLC was carried out using an analytic RP-18 column (Chromolith Speed ROD from Merck KgaA, Germany) which was operated at 40° C. Acetonitrile with 0.1% by volume of a trifluoroacetic acid/water mixture and 0.1% by volume of trifluoroacetic acid served as mobile phase; flow rate: 1.8 mL/min and injection volume: 2 μl.
2.5 g (12.9 mmol) of 1-methyl-3-trifluoromethyl-1H-pyrazole-4-carboxylic acid in 25 mL of N,N-dimethylformanid (DMF) and 2.1 g (12.9 mmol) of N,N′-carbonyl diimidazole (CDI) were stirred at ambient temperature for 1 hour prior to addition of 1.2 g (12.9 mmol) of 3-aminopyridine. After three days of stirring the solvent was evaporated, the residue dissolved in dichloromethane, washed twice with a saturated solution of NaHCO3 and water. The combined organic phases were evaporated and the crude product was purified by flash column chromatography (silica using dichloromethane/methanol=95/5) to give 1.33 g (48%) of the title compound.
1.0 g (3.7 mmol) of 1-methyl-3-trifluoromethyl-1H-pyrazole-4-carboxylic acid pyridin-3-yl-amide from example 13 in 10 mL of tetrahydrofuran (THF) and 3.7 g (11.1 mmol) of cesium carbonate were stirred at ambient temperature and 790 mg (5.55 mmol) of methyl iodide were added to the mixture. After two days of stirring the suspension was filtered, the solvent evaporated and the crude product was purified by flash column chromatography (silica using cyclohexane/ethyl acetate) to give 327 mg (31%) of the methylated amide.
Furthermore compounds 242 and 243 have been prepared according to the methods outlined above.
2. Evaluation of Pesticidal Activity:
II.1 Cotton Aphid (Aphis Gossypii, Mixed Life Stages)
The active compounds were formulated in 50:50 (vol:vol) acetone:water and 100 ppm Kinetica™ surfactant.
Cotton plants at the cotyledon stage (one plant per pot) were infested by placing a heavily infested leaf from the main colony on top of each cotyledon.
