      Moreover, the invention relates to processes and intermediates for preparing these compounds, to compositions comprising them and to their use for controlling phytopathogenic harmful fungi.  
      5-Chloro-6-phenyl-7-aminotriazolopyrimidines are known in a general manner from EP-A 71 792 and EP-A 550 113. 6-Phenyltriazolopyrimidines whose phenyl group may carry an alkylamide group in the para-position are proposed in a general manner in WO 03/080615. These compounds are known to be suitable for controlling harmful fungi.  
      The compounds according to the invention differ from those described in WO 03/080615 by the carboxamide group as substituent of the 6-phenyl ring.  
      However, the action of the known compounds is in many cases unsatisfactory. On the basis thereof, it is an object of the present invention to provide compounds having improved activity and/or a broader activity spectrum.  
      We have found that this object is achieved by the compounds defined at the outset. Moreover, we have found processes and intermediates for their preparation, compositions comprising them and methods for controlling harmful fungi using the compounds I.  
      The compounds according to the invention can be obtained by different routes. Advantageously, they are prepared by reacting 5-aminotriazol of the formula II with appropriately substituted phenylmalonates of the formula III in which R is alkyl, preferably C 1 -C 6 -alkyl, in particular methyl or ethyl.  
                 
 
      This reaction is usually carried out at temperatures of from 80° C. to 250° C., preferably from 120° C. to 180° C., without solvent or in an inert organic solvent in the presence of a base [cf. EP-A 770 615] or in the presence of acetic acid under the conditions known from Adv. Het. Chem. 57 (1993), 81 ff.  
      Suitable solvents are aliphatic hydrocarbons, aromatic hydrocarbons, such as toluene, o-, m- and p-xylene, halogenated hydrocarbons, ethers, nitrites, ketones, alcohols, and also N-methylpyrrolidone, dimethyl sulfoxide, dimethylformamide and dimethylacetamide. With particular preference, the reaction is carried out in the absence of a solvent or in chlorobenzene, xylene, dimethyl sulfoxide or N-methylpyrrolidone. It is also possible to use mixtures of the solvents mentioned.  
      Suitable bases are, in general, inorganic compounds, such as alkali metal and alkaline earth metal hydroxides, alkali metal and alkaline earth metal oxides, alkali metal and alkaline earth metal hydrides, alkali metal amides, alkali metal and alkaline earth metal carbonates, and also alkali metal bicarbonates, organometallic compounds, in particular alkali metal alkyls, alkyl magnesium halides and also alkali metal and alkaline earth metal alkoxides and dimethoxymagnesium, moreover organic bases, for example tertiary amines, such as trimethylamine, triethylamine, triisopropylethylamine, tributylamine and N-methylpiperidine, N-methylmorpholine, pyridine, substituted pyridines, such as collidine, lutidine and 4-dimethylaminopyridine, and also bicyclic amines. Particular preference is given to tertiary amines, such as triisopropylethylamine, tributylamine, N-methylmorpholine or N-methylpiperidine.  
      The bases are generally employed in catalytic amounts; however, they can also be employed in equimolar amounts, in excess or, if appropriate, as solvent.  
      The starting materials are generally reacted with one another in equimolar amounts. In terms of yield, it may be advantageous to use an excess of the base and the malonate III, based on the triazole.  
      Phenylmalonates of the formula III are advantageously obtained from the reaction of appropriately substituted bromobenzenes with dialkyl malonates under Cu(I) catalysis [cf. Chemistry Letters (1981), 367-370; EP-A 10 02 788].  
      The dihydroxytriazolopyrimidines of the formula IV are, under the conditions known from WO-A 94/20501, converted into the dihalopyrimidines of the formula V in which Hal is a halogen atom, preferably a bromine or a chlorine atom, in particular a chlorine atom. The halogenating agent [HAL] used is advantageously a chlorinating agent or a brominating agent, such as phosphorus oxybromide or phosphorus oxychloride, if appropriate in the presence of a solvent.  
                 
 
      This reaction is usually carried out at from 0° C. to 150° C., preferably from 80° C. to 125° C. [cf. EP-A 770 615].  
      Dihalopyrimidines of the formula V are reacted further with amines of the formula VI  
                 
 
 in which R 1  and R 2  are as defined in formula I, to give compounds of the formula I in which X is halogen. 
 
      This reaction is advantageously carried out at from 0° C. to 70° C., preferably from 10° C. to 35° C., preferably in the presence of an invert solvent, such as an ether, for example dioxane, diethyl ether or, in particular, tetrahydrofuran, a halogenated hydrocarbon, such as dichloromethane, or an aromatic hydrocarbon, such as, for example, toluene [cf. WO-A 98/46608].  
      The use of a base, such as a tertiary amine, for example triethylamine, or an inorganic base, such as potassium carbonate, is preferred; it is also possible for excess amine of the formula VI to serve as base.  
      Compounds of the formula I in which X is cyano, C 1 -C 6 -alkoxy or C 1 -C 2 -haloalkoxy can be obtained in an advantageous manner by reacting compounds I in which X is halogen, preferably chlorine, with compounds M-X′ (formula VII). Depending on the meaning of the group X′ to be introduced, the compounds VII are inorganic cyanides, alkoxides or haloalkoxides. The reaction is advantageously carried out in the presence of an inert solvent. The cation M in formula VII is of little importance; for practical reasons, ammonium, tetraalkylammonium or alkali metal or alkaline earth metal salts are usually preferred.  
                 
 
      The reaction temperature is usually from 0 to 120° C., preferably from 10 to 40° C. [cf. J. Heterocycl. Chem. 12 (1975), 861-863].  
      Suitable solvents include ethers, such as dioxane, diethyl ether and, preferably, tetrahydrofuran, halogenated hydrocarbons, such as dichloromethane, and aromatic hydrocarbons, such as toluene.  
      Compounds of the formula I, in which X is C 1 -C 4 -alkyl or C 1 -C 4 -haloalkyl can be obtained in an advantageous manner by the following synthesis route:  
                 
 
      Starting with the keto esters IIIa, the 5-alkyl-7-hydroxy-6-phenyltriazolopyrimidines IVa are obtained. In the formula IIIa and IVa, X 1  is C 1 -C 4 -alkyl or C 1 -C 4 -haloalkyl. By using the easily obtainable 2-phenylacetoacetates (IIIa where X 1 =CH 3 ), the 5-methyl-7-hydroxy-6-phenyltriazolopyrimidines are obtained [cf. Chem. Pharm. Bull. 9 (1961), 801]. The starting materials Ilia are advantageously prepared under the conditions described in EP-A 10 02 788.  
      The resulting 5-alkyl-7-hydroxy-6-phenyltriazolopyrimidines are reacted with halogenating agents [HAL] under the conditions described further above to give the 7-halotriazolopyrimidines of the formula Va. Preference is given to using chlorinating or brominating agents, such as phosphorus oxybromide, phosphorus oxychloride, thionyl chloride, thionyl bromide or sulfuryl chloride. The reaction can be carried out neat or in the presence of a solvent. Customary reaction temperatures are from 0 to 150° C. or, preferably, from 80 to 125° C.  
                 
 
      The reaction of Va with amines VI is carried out under the conditions described further above.  
      Alternatively, compounds of the formula I in which X is C 1 -C 4 -alkyl can also be prepared from compounds I in which X is halogen, in particular chlorine, and malonates of the formula VIII. In formula VIII, X″ is hydrogen or C 1 -C 3 -alkyl and R is C 1 -C 4 -alkyl. They are converted into compounds of the formula IX and decarboxylated to give compounds I [cf. U.S. Pat. No. 5,994,360].  
                 
 
      The malonates VIII are known from the literature [J. Am. Chem. Soc. 64 (1942), 2714; J. Org. Chem. 39 (1974), 2172; Helv. Chim. Acta, 61 (1978), 1565], or they can be prepared in accordance with the literature cited.  
      The subsequent hydrolysis of the ester IX is carried out under generally customary conditions; depending on the various structural elements, the alkaline or the acidic hydrolysis of the compounds IX may be advantageous. Under the conditions of the ester hydrolysis, there may already be complete or partial decarboxylation to I.  
      The decarboxylation is usually carried out at temperatures of from 20° C. to 180° C., preferably from 50° C. to 120° C., in an inert solvent, if appropriate in the presence of an acid.  
      Suitable acids are hydrochloric acid, sulfuric acid, phosphoric acid, formic acid, acetic acid, p-toluenesulfonic acid. Suitable solvents are water, aliphatic hydrocarbons, such as pentane, hexane, cyclohexane and petroleum ether, aromatic hydrocarbons, such as toluene, o-, m- and p-xylene, halogenated hydrocarbons, such as methylene chloride, chloroform and chlorobenzene, ethers, such as diethyl ether, diisopropyl ether, tert-butyl methyl ether, dioxane, anisole and tetrahydrofuran, nitriles, such as acetonitrile and propionitrile, ketones, such as acetone, methyl ethyl ketone, diethyl ketone and tert-butyl methyl ketone, alcohols, such as methanol, ethanol, n-propanol, isopropanol, n-butanol and tert-butanol, and also dimethyl sulfoxide, dimethylformamide and dimethylacetamide; particularly preferably, the reaction is carried out in hydrochloric acid or acetic acid. It is also possible to use mixtures of the solvents mentioned.  
      Compounds of the formula I in which X is C 1 -C 4 -alkyl can also be obtained by coupling 5-halotriazolopyrimidines of the formula I in which X is halogen with organometallic reagents of the formula X. In one embodiment of this process, the reaction is carried out with transition metal catalysis, such as Ni or Pd catalysis.  
                 
 
      In formula X, M is a metal ion of the valency y, such as, for example, B, Zn or Sn, and X″ is C 1 -C 3 -alkyl. 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. 43 (1990), 733; J. Org. Chem. 43 (1978), 358; J. Chem. Soc. Chem. Commun. (1979), 866; Tetrahedron Lett. 34 (1993), 8267; ibid 33 (1992), 413.  
      Alternatively, compounds of the formula I can also be prepared from substituted 6-cyanophenyltriazolopyrimidines of the formula XI.  
                 
 
      This reaction can be carried out in the presence of sulfuric acid at from 0 to 60° C., in particular from 20 to 25° C. [cf. Synthetic Commun. (1999), 547 ff.], alternatively, the reaction can be carried out in the system polyethylene glycol/NaOH at from 0 to 60° C., in particular from 20 to 25° C., in the presence of a solvent or diluent [cf. Synthetic Commun. (2000), 1713 ff.], or using urea/hydrogen peroxide at from 0 to 60° C., in particular from 20 to 25° C., in the presence of a solvent or diluent [cf. Org. Lett. (1999), 189 ff.].  
      Compounds of the formula XI are known from WO 03/080615 and/or can be prepared in accordance with the literature cited.  
      Moreover, the compounds of the formula I can be prepared by Pd-catalyzed aminocarbonylation [cf. Tetrahedron Lett. 39 (1988), 2835-2838; J. Org. Chem. 66, (2001), 4311 ff; WO 00/37428; DE 35 25 564; J. Org. Chem. 62 (1997), 8640-8653; JP 2000191612) of the corresponding halogen compounds XII [cf. EP-A 550113] or triflate XIII.  
                 
 
      The reaction mixtures are worked up in a customary manner, for example by mixing with water, separating the phases and, if appropriate, chromatographic purification of the crude products. Some of the intermediates and end products are obtained in the form of colorless or slightly brownish viscous oils which are purified or freed from volatile components under reduced pressure and at moderately elevated temperature. If the intermediates and end products are obtained as solids, purification can also be carried out by recrystallization or digestion.  
      If individual compounds I cannot be obtained by the routes described above, they can be prepared by derivatization of other compounds I.  
      If the synthesis yields mixtures of isomers, a separation is generally not necessarily required since in some cases the individual isomers can be interconverted during work-up for use or during application (for example under the action of light, acids or bases). Such conversions may also take place after use, for example in the treatment of plants in the treated plant, or in the harmful fungus to be controlled.

      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, maize, grass, bananas, cotton, soya, 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,      Pyricularia oryzae  on rice,      Rhizoctonia  species on cotton, rice and lawns,      Septodia tritici  and  Stagonospora nodorum  on wheat,      Uncinula necator  on grapevines,      Ustilago  species on cereals and sugar cane, and      Venturia  species (scab) on apples and pears.        

      The compounds I are also suitable for controlling harmful fungi, such as  Paecilomyces variotii , in the protection of materials (e.g. 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 from 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 1 to 1000 g/100 kg of seed, preferably 1 to 200 g/100 kg, in particular 5 to 100 g/100 kg are generally required.  
      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 into the customary formulations, for example solutions, emulsions, suspensions, dusts, powders, pastes and granules. The application form depends on the particular purpose; in each case, it should 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 octylphenol ether, ethoxylated isooctylphenol, octylphenol, nonylphenol, alkylphenol 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.  
      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

      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. Current 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 the use forms prepared therefrom, for example in the form of directly sprayable solutions, powders, suspensions or dispersions, emulsions, oil dispersions, pastes, dustable products, materials for spreading, or granules, by means of spraying, atomizing, dusting, spreading or pouring. The use forms depend entirely on the intended purposes; the intention is to ensure in each case the finest possible distribution of the active compounds 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. Alternatively, it is 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%.  
      The active compounds may also be used successfully in the ultra-low-volume process (ULV), by which it is possible to apply formulations comprising over 95% by weight of active compound, or even to apply the active compound without additives.  
      Various types of oils, wetters, adjuvants, herbicides, fungicides, other pesticides, or bactericides may be added to the active compounds, if appropriate not until immediately prior to use (tank mix). These agents can be admixed with the agents according to the invention in a weight ratio of 1:10 to 10:1.  
      The compositions according to the invention can, in the use form as fungicides, also be present together with other active compounds, e.g. with herbicides, insecticides, growth regulators, fungicides or else with fertilizers. Mixing the compounds I or the compositions comprising them in the application form as fungicides with other fungicides results in many cases in an expansion of the fungicidal spectrum of activity being obtained.

 Examples for the Action Against Harmful Fungi 
 
      The fungicidal action of the compounds of the formula I was demonstrated by the following tests:  
      The active compounds were prepared 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, and the mixture was diluted with water to the desired concentration.  
     Use Example 1—Activity Against Net Blotch of Barley Caused by  Pyrenophora teres    
      Leaves of pot-grown barley seedlings of the cultivar “Hanna” were sprayed to runoff point with an aqueous suspensiori having the concentration of active compound stated below. 24 hours after the spray coating had dried on, the test plants were inoculated with an aqueous spore suspension of  Pyrenophora  [syn.  Drechslera] teres , the causative agent of net blotch. The test plants were subsequently placed in a greenhouse at temperatures of between 20 and 24° C. and at a relative atmospheric humidity of 95 to 100%. After 6 days, the extent of the development of the disease was determined visually in % of infection of the total leaf area.  
      In this test, the plants which had been treated with 63 ppm of the compounds I-1 or I-25 showed an infection of only about 3%, whereas the untreated plants were 90% infected.  
     Use Example 2—Activity Against Peronospora of Vines Caused by  Plasmopara viticola    
      Leaves of potted vines of the cultivar “Riesling” were sprayed to runoff point with an aqueous suspension having the concentration of active compounds stated below. The next day, the undersides of the leaves were inoculated with an aqueous zoospore suspension of  Plasmopara viticola . The vines were then initially placed in a water-vapor-saturated chamber at 24° C. for 48 hours and then in a greenhouse at temperatures of between 20 and 30° C. for 5 days. After this time, the plants were again placed in a moist chamber for 16 hours to promote sporangiophore eruption. The extent of the development of the infection on the undersides of the leaves was then determined visually.  
      In this test, the plants which had been treated with 250 ppm of the title compound from example 1 showed no infection, whereas the untreated plants were 90% infected.  
     Use Example 3—Activity Against Gray Mold on Bell-pepper Leaves Caused by  Botrytis cinerea , Protective Application  
      Bell-pepper seedlings of the cultivar “Neusiedler Ideal Elite ” were, after 2 to 3 leaves were well developed, sprayed to run-off point with an aqueous suspension having the concentration of active compounds stated below. The next day, the treated plants were inoculated with a spore suspension of  Botrytis cinerea  which contained 1.7×10 6  spores/ml in a 2% aqueous biomold solution. Test plants were then placed in a dark climatized chamber at 22 to 24° C. and high atmospheric humidity. After 5 days, the extent of the fungal infection on the leaves could be determined visually in %.  
      In this test, the plants which had been treated with 63 ppm of the compounds I-2, I-14, I-23, I-24 or I-25 showed an infection of not more than 30%, whereas the untreated plants were 75% infected.
