Moreover, the invention relates to a process for preparing these compounds, to compositions comprising 2-pyrimidines and to their use for controlling phytopathogenic harmful fungi.
Fungicidal pyrimidines carrying a cyanamino substituent in the 2-position are known from WO-A 01/96314. Furthermore, fungicidal 2-pyrimidyl-N-methoxyamidines are known from WO-A 03/43993.
However, in many cases the activity of the abovementioned pyrimidines is unsatisfactory. It is an object of the present invention to provide compounds having improved activity.
We have found that this object is achieved by the pyrimidines of the formula I defined at the outset. Moreover, we have found processes for their preparation and compositions comprising them for controlling harmful fungi.
The compounds I can be obtained by different routes.

    1) It is possible, for example, to use sulfones of the formula 11 whose preparation is described in detail in WO-A 02/074753 or DE 10156279.9 as starting materials. Reaction of the sulfones II with metal cyanides III (Me+CN−) yields the nitriles IV. Metal cyanides are to be understood as meaning primarily alkali metal cyanides or alkaline earth metal cyanides or else covalent cyanides, such as tin tetracyanide.






The exchange of the sulfonate group for the nitrile group is carried out by methods known from the literature, as described, for example, in WO-A 03/043993.
The further synthesis can be carried out as shown in Scheme 1:




The nitrile compound IV can be hydrolyzed to the amide IA under acidic or, preferably, basic conditions. The hydrolysis is carried out, for example, under the conditions described by Katritzky et al. in Synthesis 1989, pp. 949-950 (hydrogen peroxide, base, polar aprotic solvent). Hydrolyses of nitriles to amides under acidic conditions are described in Comprehensive Organic Chemistry, Vol 2, Sutherland, I.O. Pergamon Press, Oxford, 1979, p. 964.
Alternatively, the Pinner adduct, which is generated when in general hydrochloric acid forms an adduct with nitrile IV, can be reacted with an alcohol of the formula RbOH, where Rb is as defined above, to give the imino ether of the formula IB. The alkylation with RaX—Y, where Ra and the bridge X are as defined above and y is a leaving group such as halide, sulfate or sulfonate, gives compounds of type IC.
The alkylation with Ra—Y starting with compound IB or the nitrile IV can also be carried out using Meerwein salts of the formula (Ra)3OBF4 analogously to the procedures given in Synth. Commun., 1983, 13, p. 753 or Helv. Chim. Acta, 1986, 69, p. 1224. This affords compounds I in which X is a direct bond.
An alternative synthesis of the compounds IA according to the invention is shown in Scheme 2.




The synthesis, shown in Scheme 2, of the compounds IA′ and IC in turn uses nitrile IV as starting material. The nitrile IV can preferably be prepared under acidic conditions in the presence of alcohols of the formula R′OH, where R′ is C1-C8-alkyl, C2-C8-alkenyl, C2-C8-alkynyl or C3-C6-cycloalkyl, where the radicals alkyl, alkenyl and alkynyl may be partially or fully halogenated and may carry one to three groups Rv. The reaction of V with amines to give the amides IA′ can be carried out as described in Org. Lett., 2001, Vol 3, p. 1053-56 or in J. Org. Chem., 2000, Vol 85, p. 8415-20. The subsequent reaction with Meerwein salts of the formula (Rb)3OBF4 analogously to the procedures given in Synth. Commun., 1983, 13, p. 753 or Helv. Chim. Acta, 1986, 69, p. 1224 yields the compounds of the formula IC according to the invention. The imine halides of the formula VI where Hal is halogen and in particular chlorine or bromine can be obtained analogously to Synthesis, 1991, Vol 9, p. 750-752. In an Appel reaction using, for example, carbon tetrabromide and triphenylphosphine, the corresponding bromine compounds are prepared. The latter can finally be reacted with alcohols of the formula RbOH and base to give the compounds IC according to the invention.
The radical R3 (in particular alkyl) in the 6-position on the pyrimidine ring can be introduced by reaction with transition metal catalysis, such as Ni or Pd catalysis. In some cases it may be advisable to change the order and to introduce the substituent R3 prior to the substituent NR1R2.




In the formula (R3)y-wXw-My, M is a metal ion of valency Y, such as, for example, B, Zn, Mg, Cu or Sn, X is chlorine, bromine, iodine or hydroxy, R3 is preferably C1-C4-alkyl and w is a number from 0 to 3. This reaction can be carried out, for example, analogously to the following methods: J. Chem. Soc., Perkin Trans. 1 (1994), 1187, ibid.1 (1996), 2345; WO-A 99/41255; Aust. J. Chem. vol. 43 (1990), 733; J. Org. Chem. vol. 43 (1978), 358; J. Chem. Soc., Chem. Commun. (1979), 866; Tetrahedron Lett. vol. 34 (1993), 8267; ibid. vol. 33 (1992), 413.
The substituent Ra in formula IA′ can also be introduced as shown in Scheme 4.




Here, the compounds of the formula IA are initially converted with the aid of strong bases into the anion and then reacted with the corresponding acid chlorides to give IA′ (see J. Chem. Soc., Perkin Trans I, 1995, p. 3043). This gives compounds in which X is a C═O bridge. Bases suitable for preparing the anion are, for example, sodium amide and sodium hydride.
What was said above refers in particular to the preparation of compounds in which R3 is an alkyl group. If R3 is a cyano group or an alkoxy substituent, the radical R3 can be introduced by reaction with alkali metal cyanides and alkali metal alkoxides, respectively.

With a view to the intended use of the pyrimidines of the formula I, particular preference is given to the following meanings of the substituents, in each case on their own or in combination:
Preference is given to compounds I in which R1 is C1-C6-alkyl, C1-C6-haloalkyl, C2-C6-alkenyl, C2-C6-alkynyl or C3-C6-cycloalkyl and R2 is hydrogen.

In addition, preference is given to compounds I in which R1 is C1-C4-haloalkyl and R2 is hydrogen.

Particular preference is also given to compounds I in which R3 is C1-C4-alkyl which may be substituted by halogen.
Moreover, particular preference is given to compounds I in which R3 is halogen, cyano, C1-C4-alkyl or C1-C4-alkoxy.
Especially preferred are compounds I in which R3 is methyl, cyano, methoxy or in particular chlorine.
Suitable with a view to their fungicidal action are pyrimidines of the formula I in which R4 is




Preference is furthermore given to pyrimidines of the formula I in which R4 is




Especially preferred are pyrimidines of the formula I in which R4 is




Finally, R4 may preferably have the following meanings which may also be interpreted as definitions of prodrug radicals (see Medicinal Research Reviews 2003, 23, 763-793, or J. of Pharmaceutical Sciences 1997, 86, 765-767):




The index n in the alkenylene radicals of the above formulae is an integer from 1 to 3. Especially preferred are the following radical definitions R4:




The bridge X is preferably a direct bond or —(C═O)—.
The substituent Ra is preferably hydrogen, methyl, benzyl, trifluoromethyl, allyl, propargyl or methoxymethyl and particularly preferably hydrogen.
The substituent Rb is preferably hydrogen, C1-C6-alkyl or C2-C6-alkenyl and particularly preferably: methyl, allyl or propargyl.
The substituent Rc is preferably hydrogen or methyl.
The esters of the formula V




are both interesting intermediates and excellent fungicidally active compounds.

The preferences in the definitions of Ln and R1 to R3 mentioned above apply correspondingly to the esters of the formula V.
R′ is in particular a C1-C6-alkyl radical, especially preferably an isopropyl radical.
However, R′ may also have the meanings allyl, propargyl, benzyl, aminoalkyl, hydroxyalkyl, alkoxyalkyl or haloalkyl.
In particular with a view to their use, preference is given to compounds I and V compiled in the tables below. Moreover, the groups mentioned for a substituent in the tables are per se, independently of the combination in which they are mentioned, a particularly preferred embodiment of the substituent in question.

The compounds I are suitable as fungicides. They are distinguished by an outstanding effectiveness against a broad spectrum of phytopathogenic fungi, especially from the classes of the Ascomycetes, Deuteromycetes, Oomycetes and Basidiomycetes. Some are systemically effective and they can be used in plant protection as foliar and soil fungicides.
They are particularly important in the control of a multitude of fungi on various cultivated plants, such as wheat, rye, barley, oats, rice, corn, grass, bananas, cotton, soybean, coffee, sugar cane, vines, fruits and ornamental plants, and vegetables, such as cucumbers, beans, tomatoes, potatoes and cucurbits, and on the seeds of these plants.
They are especially suitable for controlling the following plant diseases:

    Alternaria species on fruit and vegetables,
    Bipolaris and Drechslera species on cereals, rice and lawns,
    Blumeria graminis (powdery mildew) on cereals,
    Botrytis cinerea (gray mold) on strawberries, vegetables, ornamental plants and grapevines,
    Erysiphe cichoracearum and Sphaerotheca fuliginea on cucurbits,
    Fusarium and Verticillium species on various plants,
    Mycosphaerella species on cereals, bananas and peanuts,
    Phytophthora infestans on potatoes and tomatoes,
    Plasmopara viticola on grapevines,
    Podosphaera leucotricha on apples,
    Pseudocercosporella herpotrichoides on wheat and barley,
    Pseudoperonospora species on hops and cucumbers,
    Puccinia species on cereals,

The compounds I are also suitable for controlling harmful fungi, such as Paecilomyces variotii, in the protection of materials (for example wood, paper, paint dispersions, fibers or fabrics) and in the protection of stored products.
The compounds I are employed by treating the fungi or the plants, seeds, materials or soil to be protected against fungal attack with a fungicidally effective amount of the active compounds. The application can be carried out both before and after the infection of the materials, plants or seeds by the fungi.
The fungicidal compositions generally comprise between 0.1 and 95%, preferably between 0.5 and 90%, by weight of active compound.
When employed in plant protection, the amounts applied are, depending on the kind of effect desired, between 0.01 and 2.0 kg of active compound per ha.
In seed treatment, amounts of active compound of 0.001 to 0.1 g, preferably 0.01 to 0.05 g, per kilogram of seed are generally necessary.
When used in the protection of materials or stored products, the amount of active compound applied depends on the kind of application area and on the desired effect. Amounts customarily applied in the protection of materials are, for example, 0.001 g to 2 kg, preferably 0.005 g to 1 kg, of active compound per cubic meter of treated material.
The compounds I can be converted to the customary formulations, for example solutions, emulsions, suspensions, dusts, powders, pastes and granules. The application form depends on the particular intended use; it should in each case ensure a fine and uniform distribution of the compound according to the invention.
The formulations are prepared in a known manner, for example by extending the active compound with solvents and/or carriers, if desired using emulsifiers and dispersants. Solvents/auxiliaries which are suitable are essentially:
water, aromatic solvents (for example Solvesso products, xylene), paraffins (for example mineral oil fractions), alcohols (for example methanol, butanol, pentanol, benzyl alcohol), ketones (for example cyclohexanone, gamma-butyrolactone), pyrrolidones (NMP, NOP), acetates (glycol diacetate), glycols, fatty acid dimethylamides, fatty acids and fatty acid esters. In principle, solvent mixtures may also be used.

    
    
        carriers such as ground natural minerals (for example kaolins, clays, talc, chalk) and ground synthetic minerals (for example highly disperse silica, silicates); emulsifiers such as nonionic and anionic emulsifiers (for example polyoxyethylene fatty alcohol ethers, alkylsulfonates and arylsulfonates) and dispersants such as lignosulfite waste liquors and methylcellulose.
    
    


Suitable surfactants are alkali metal, alkaline earth metal and ammonium salts of lignosulfonic acid, naphthalenesulfonic acid, phenolsulfonic acid, dibutylnaphthalenesulfonic acid, alkylarylsulfonates, alkyl sulfates, alkylsulfonates, fatty alcohol sulfates, fatty acids and sulfated fatty alcohol glycol ethers, furthermore condensates of sulfonated naphthalene and naphthalene derivatives with formaldehyde, condensates of naphthalene or of naphthalenesulfonic acid with phenol and formaldehyde, polyoxyethylene octylphenyl ether, ethoxylated isooctylphenol, octylphenol, nonylphenol, alkylphenyl polyglycol ethers, tributylphenyl polyglycol ether, tristearylphenyl polyglycol ether, alkylaryl polyether alcohols, alcohol and fatty alcohol/ethylene oxide condensates, ethoxylated castor oil, polyoxyethylene alkyl ethers, ethoxylated polyoxypropylene, lauryl alcohol polyglycol ether acetal, sorbitol esters, lignosulfite waste liquors and methylcellulose.
Substances which are suitable for the preparation of directly sprayable solutions, emulsions, pastes or oil dispersions are mineral oil fractions of medium to high boiling point, such as kerosene or diesel oil, furthermore coal tar oils and oils of vegetable or animal origin, aliphatic, cyclic and aromatic hydrocarbons, for example toluene, xylene, paraffin, tetrahydronaphthalene, alkylated naphthalenes or their derivatives, methanol, ethanol, propanol, butanol, cyclohexanol, cyclohexanone, isophorone, strongly polar solvents, for example dimethyl sulfoxide, N-methylpyrrolidone and water.
Powders, materials for spreading and dustable products can be prepared by mixing or concomitantly grinding the active substances with a solid carrier.
Granules, for example coated granules, impregnated granules and homogeneous granules, can be prepared by binding the active compounds to solid carriers. Examples of solid carriers are mineral earths such as silica gels, silicates, talc, kaolin, attaclay, limestone, lime, chalk, bole, loess, clay, dolomite, diatomaceous earth, calcium sulfate, magnesium sulfate, magnesium oxide, ground synthetic materials, fertilizers, such as, for example, ammonium sulfate, ammonium phosphate, ammonium nitrate, ureas, and products of vegetable origin, such as cereal meal, tree bark meal, wood meal and nutshell meal, cellulose powders and other solid carriers.
In general, the formulations comprise from 0.01 to 95% by weight, preferably from 0.1 to 90% by weight, of the active compound. The active compounds are employed in a purity of from 90% to 100%, preferably 95% to 100% (according to NMR spectrum).
The following are examples of formulations:
1. Products for Dilution with Water
A) Water-Soluble Concentrates (SL)
10 parts by weight of a compound according to the invention are dissolved in water or in a water-soluble solvent. As an alternative, wetters or other auxiliaries are added. The active compound dissolves upon dilution with water.
B) Dispersible Concentrates (DC)
20 parts by weight of a compound according to the invention are dissolved in cyclohexanone with addition of a dispersant, for example polyvinylpyrrolidone. Dilution with water gives a dispersion.
C) Emulsifiable Concentrates (EC)
15 parts by weight of a compound according to the invention are dissolved in xylene with addition of calcium dodecylbenzenesulfonate and castor oil ethoxylate (in each case 5% strength). Dilution with water gives an emulsion.
D) Emulsions (EW, EO)
40 parts by weight of a compound according to the invention are dissolved in xylene with addition of calcium dodecylbenzenesulfonate and castor oil ethoxylate (in each case 5% strength). This mixture is introduced into water by means of an emulsifier (Ultraturvax) and made into a homogeneous emulsion. Dilution with water gives an emulsion.
E) Suspensions (SC, OD)
In an agitated ball mill, 20 parts by weight of a compound according to the invention are comminuted with addition of dispersants, wetters and water or an organic solvent to give a fine active compound suspension. Dilution with water gives a stable suspension of the active compound.
F) Water-Dispersible Granules and Water-Soluble Granules (WG, SG)
50 parts by weight of a compound according to the invention are ground finely with addition of dispersants and wetters and made into water-dispersible or water-soluble granules by means of technical appliances (for example extrusion, spray tower, fluidized bed). Dilution with water gives a stable dispersion or solution of the active compound.
G) Water-Dispersible Powders and Water-Soluble Powders (WP, SP)
75 parts by weight of a compound according to the invention are ground in a rotor-stator mill with addition of dispersants, wetters and silica gel. Dilution with water gives a stable dispersion or solution of the active compound.
2. Products to be Applied Undiluted
H) Dusts (DP)
5 parts by weight of a compound according to the invention are ground finely and mixed intimately with 95% of finely divided kaolin. This gives a dustable product.
I) Granules (GR, FG, GG, MG)
0.5 part by weight of a compound according to the invention is ground finely and associated with 95.5% carriers. Customary methods are extrusion, spray-drying or the fluidized bed. This gives granules to be applied undiluted.
J) ULV Solutions (UL)
10 parts by weight of a compound according to the invention are dissolved in an organic solvent, for example xylene. This gives a product to be applied undiluted.
The active compounds can be used as such, in the form of their formulations or of the application forms prepared therefrom, e.g. in the form of directly sprayable solutions, powders, suspensions or dispersions, emulsions, oil dispersions, pastes, dustable products, preparations for broadcasting or granules, by spraying, atomizing, dusting, broadcasting or watering. The application forms depend entirely on the intended uses; they should always ensure the finest possible dispersion of the active compounds according to the invention.
Aqueous application forms can be prepared from emulsifiable concentrates, pastes or wettable powders (spray powders, oil dispersions) by addition of water. To prepare emulsions, pastes or oil dispersions, the substances can be homogenized in water, as such or dissolved in an oil or solvent, by means of wetting agents, tackifiers, dispersants or emulsifiers. However, it is also possible to prepare concentrates comprising active substance, wetting agent, tackifier, dispersant or emulsifier and possibly solvent or oil which are suitable for dilution with water.
The concentrations of active compound in the ready-for-use preparations can be varied within relatively wide ranges. In general, they are between 0.0001 and 10%, preferably between 0.01 and 1%.
The active compounds can also be used with great success in the ultra-low volume (ULV) process, it being possible to apply formulations with more than 95% by weight of active compound or even the active compound without additives.
Oils of various types, wetting agents, adjuvants, herbicides, fungicides, other pesticides and bactericides can be added to the active compounds, if need be also not until immediately before use (tank mix). These agents can be added to the preparations according to the invention in a weight ratio of 1:10 to 10:1.
The preparations according to the invention can, in the application form as fungicides, also be present together with other active compounds, e.g. with herbicides, insecticides, growth regulators, fungicides or also with fertilizers. On mixing the compounds I or the preparations comprising them in the application form as fungicides with other fungicides, in many cases an expansion of the fungicidal spectrum of activity is obtained.

SYNTHESIS EXAMPLES 
Example 1
Preparation of 4-chloro-6-((S)-2,2,2-trifluoro-1-methylethylamino)-5-(2,4,6-trifluorophenyl)-pyrimidine-2-carboxamide [I-5]




5.0 g of 4-chloro-6-((S)-2,2,2-trifluoro-1-methylethylamino)-5-(2,4,6-trifluorophenyl)-pyrimidine-2-carbonitrile (see WO 03/04993, pages 28 and 29) were initially charged in 5 ml of DMSO, 344 mg of K2CO3 were added and the mixture was cooled to 10° C. 1.4 ml of 30% strength H2O2 were then added. The mixture was stirred in an ice bath for 5 min and then at room temperature for another 30 min. The reaction mixture was introduced into 150 ml of water. During the addition, the amide precipitated out. The amide was filtered off, washed and dried under high vacuum. This gave 4.7 g of the beige title compound of m.p. 157-162° C.
Example 2
Preparation of 4-chloro-6-((S)-2,2,2-trifluoro-1-methylethylamino)-5-(2,4,6-trifluorophenyl)-pyrimidine-2-carboxylic acid [I-11]




1.5 g of 4-chloro-6-((S)-2,2,2-trifluoro-1-methylethylamino)-5-(2,4,6-trifluorophenyl)-pyrimidine-2-carbonitrile (see WO 03/04993, pages 28 and 29) were dissolved in 5 ml of conc. H2SO4, and the mixture was stirred at 110° C. for 20 min. The reaction mixture was introduced into 100 ml of ice-water, and during the addition the acid precipitated out. The acid was filtered off, washed with water and dried under high vacuum. This gave 1.5 g of the yellow title compound.
1H-NMR (CDCl3, ppm): 1.4 (d, CH3), 4.85 (d, NH), 5.60-5.80 (m, CH), 6.90-7.00 (m, CH), 10.5 (s (broad), OH).
Example 3
Preparation of N-tert.-butyl-4-chloro-6-((S)-2,2,2-trifluoro-1-methyl-ethylamino)-5-(2,4,6-trifluorophenyl)pyrimidine-2-carboxamide [I-10]




    
    
        a) 1.5 g of the acid (Example 2) were added to 5 ml of thionyl chloride at 40° C. The reaction mixture was stirred until the evolution of gas had ceased. Toluene was added to the mixture and the solvent and excess thionyl chloride were distilled off completely. This gave 1.6 g of a dark-green oil.
        b) 38 mg of tert-butylamine and 58 mg of triethylamine were initially charged in 7 ml of THF at 0° C., and 200 mg of the acid chloride prepared beforehand, dissolved in 2 ml of THF, were added. The reaction mixture was stirred at room temperature for 12 h. The reaction mixture was concentrated using a rotary evaporator, taken up in methyl tert-butyl ether and washed with water. The organic phase was removed, dried over MgSO4 and concentrated. The crude product was purified by preparative HPLC. This gave 21 mg of the yellow title compound of m.p. 49-54° C.
    
    


Example 4
Preparation of N-acetyl-4-chloro-6-((S)-2,2,2-trifluoro-1-methylethylamino)-5-(2,4,6-trifluorophenyl)-pyrimidine-2-carboximide [I-12]




With ice bath cooling, 150 mg of amide (Example 1) in 10 ml of THF were reacted with 20 mg of sodium hydride, and the mixture was stirred for 30 min. 35 mg of acetyl chloride, dissolved in 1 ml of THF, were added slowly. The reaction mixture was stirred at room temperature for 30 min. Ice-water was then added to the reaction mixture, and the mixture was extracted with dichloromethane. The combined organic phases were dried over Mg2SO4 and concentrated using a rotary evaporator. This gave 65 mg of the red-brown title compound of m.p. 58-65° C.
Example 5
Preparation of isopropyl 4-chloro-6-((S)-2,2,2-trifluoro-1-methylethylamino)-5-(2,4,6-trifluorophenyl)pyrimidine-2-carboxylate [V-3]




At room temperature, 22 g of 4-chloro-6-((S)-2,2,2-trifluoro-1-methylethylamino)-5-(2,4,6-trifluorophenyl)pyrimidine-2-carbonitrile were dissolved in 210 ml of isopropanol. Over a period of 30 min, HCl gas was introduced into the solution, and the mixture was then stirred at reflux for 96 h. The mixture was concentrated, water was added, followed by a top-layer of ethyl acetate, and the mixture was made alkaline using sodium carbonate. The ethyl acetate phase was dried with magnesium sulfate and concentrated using a rotary evaporator. This gave 21.4 g of a colorless solid.
Yield: 83.8%. m.p.: 146-147° C.

Examples of the action against harmful fungi
The fungicidal action of the compounds of the formula I was demonstrated by the following experiments:
The active compounds were prepared separately as a stock solution with 0.25% by weight of active compound in acetone or DMSO. 1% by weight of the emulsifier Uniperol® EL (wetting agent having emulsifying and dispersing action based on ethoxylated alkylphenols) was added to this solution. The stock solutions of the active compounds were diluted with water to the stated concentration.
USE EXAMPLES
1. Activity Against Late Blight on Tomatoes Caused by Phytophthora infestans, Protective Treatment
Leaves of potted plants of the cultivar “Goldene Prinzessin” were sprayed to runoff point with an aqueous suspension having the concentration of active compound stated below. The next day, the leaves were infected with an aqueous sporangiophore suspension of Phytophthora infestans. The plants were then placed in a water-vapor-saturated chamber at 18-20° C.
