The preparation of compounds of the formulae l a , l aa , l b and l bb in which R 1 f R 2 , Re and W have the meanings given under formula I, R 2 preferably being halogen, is illustrated in reaction scheme 1 which follows. Reaction scheme 1 : O " IV 1) anhydride, R 6 - solvent V 2) H 2 0 base, solvent Katada reaction ( R 2 =CI) bb l aa ( R 2 =CI) The pyridine N-oxides of the formula IV (reaction scheme 1 ) can be prepared by known methods (for example Org. Synth. 4 (1963), 828; ibid. 3 (1955), 619; US-A-3 047 579; and B. Iddon and H. Suschitzky in "Polychloroaromatic Compounds", Editor H. Suschitzky, Plenum Press, London 1974, page 197), expediently by reacting the pyridine derivatives of the formula III with oxidants such as, for example, organic peracids, for example m- chloroperbenzoic acid (MCPBA), peracetic acid and pertrifluoroacetic acid, or aqueous hydrogen peroxide solution or hydrogen peroxide/urea adduct together with carboxylic acids and/or carboxylic anhydrides, or inorganic peracids, for example pertungstic acid (Caro's acid). Suitable solvents are, for example, water, organic acids such as, for example, acetic acid and trifluoroacetic acid, halogenated hydrocarbons such as, for example, dichloromethane and 1 ,2-dichloroethane, esters, such as, for example, ethyl acetate, ethers such as, for example, tetrahydrofuran and dioxane, or mixtures of these. The reaction temperatures are in the range of -20°C to 100°C, depending on the solvent or solvent mixture used. The 6-hydroxypyridine derivatives of the formula l b can be prepared by known methods (for example Quart. Rev. 10 (1956), 395; J. Am. Chem. Soc. 85 (1963), 958; and J. Org. Chem. 26 (1961 ), 428), expediently by means of subjecting the pyridine N-oxides of the formula IV to a rearrangement reaction in the presence of anhydrides, for example acetic anhydride, trifluoroacetic anhydride and methanesulfonic anhydride, in a suitable inert solvent such as, for example, halogenated hydrocarbons, e.g. dichloromethane and 1 ,2-dichloroethane, amides, e.g. N,N-dimethylformamide and 1 -methyl-2-pyrrolidone (NMP), if appropriate in the presence of sodium acetate. The reaction temperatures are generally in the range of from -30°C to 80°C. The same reaction, in particular where R 2 is chlorine, also gives the isomeric 6-chloro-5-hydroxypyridine derivatives of the formula l bb by further rearranging the N-oxides of the formula IV. The primary products 6-O-acyl- or 6-O-sulfonylpyridines can be hydrolyzed readily by means of aqueous work-up of the reaction mixture to give the desired 6-hydroxypyridines of the formula l b . Similarly to Tetrahedron 37 (1981 ), 187, antimony pentachloride (Katada reaction) is also suitable for the above rearrangement reaction as further variant. The same applies to the isomeric 5-O-acylated derivatives. If appropriate, the isomers of the formula l b or l bb can be separated by known methods. However, they may also be reacted further as isomer mixture, the compounds of the formulae l a , l aa and II being obtained under identical reaction conditions. The subsequent alkylation can be effected by known methods (for example Org. Prep. Proced. Int. 9 (1977), 5; J. Org. Chem. 35 (1970), 2517; ibid. 32 (1967), 4040; and Tetrahedron Lett. 36 (1995), 8917, and Preparation Example H6), expediently with the aid of an alkylating reagent of the formula V. As a rule, alkylation leads to an isomer mixture composed of the compounds of the formulae l a and, if appropriate, l aa (O-alkylation) and II (N-alkylation). A further variant of preparing the alkylation products is to react the hydroxypyridines of the formula l or l bb with an alcohol of the formula R 6 OH in which R 6 has the meaning given under formula I in an inert solvent such as, for example, tetrahydrofuran, dioxane or dimethoxyethane in the presence of a phosphine such as, for example, triphenylphosphine and an azodicarboxylic acid derivative such as, for example, diethyl azodicarboxylate. Such Mitsunobu reactions are described, for example, in Tetrahedron Letters 1994, 2819. Suitable solvents are, for example, alcohols, e.g. methanol, ethanol and isopropanol, amides, e.g. N,N-dimethylformamide (DMF) and 1 -methyl-2-pyrrolidone (NMP), sulfoxides, e.g. dimethyl sulfoxide (DMSO) and sulfones, e.g. sulfolane, or mixtures of these with water, ethers, e.g. diethyl ether, tert-butyl methyl ether, dimethoxyethane (DME), dioxane and tetrahydrofuran (THF), esters, e.g. ethyl acetate, ketones, e.g. acetone and methyl ethyl ketone, and hydrocarbons, e.g. n-hexane, toluene and xylenes. Suitable bases are organic and inorganic bases such as, for example, alkali metal alkoxides, e.g. sodium methoxide, sodium ethoxide and potassium tert-butoxide, trialkylammonium hydroxides, trialkylammonium halides, e.g. triethylammonium iodide, alkali metal and alkaline earth metal hydrides, e.g. sodium hydride together with lithium bromide (2 equivalents), alkali metal carbonates, e.g. potassium carbonate, alkali metal hydroxides, e.g. sodium hydroxide and potassium hydroxide, and caesium fluoride. The reaction temperatures for the alkylation are in the range of from -20°C to reflux temperature of the solvent used, preferably 0°C to 100°C. The isomers of the formulae l a> l aa , l bb and II can be separated readily by silica gel chromatography or fractional crystallization. If appropriate, the desired pyridine derivatives of the formulae l a , l aa and It*, which have been separated from the by-product of the formula II, can readily be functionalized further by known methods in accordance with the definition of R 3 under formula I. The preparation of the compounds of the formula l c in which R^ R , R 9 , ni and W have the meanings given under formula I is illustrated in reaction scheme 2 which follows. Reaction scheme 2: sulfur reagent, e.g. B 2 H 2 S, Na+HS or NH 2 C(S)NH 2 , solvent, base VI In accordance with reaction scheme 2, the 6-halopyridines of the formula VI can be obtained from the corresponding 6-hydroxypyridines of the formula l b by means of halogenation, for example by means of phosphorus oxychloride or phenyl dichlorophosphate, if appropriate in the presence of a base in an inert solvent, by methods similar to "Pyridine and its Derivatives", Part 2, Editor E. Klingsberg, New York 1961 , page 326 et seq. The 6-halopyridines of the formula VI can be converted into the corresponding 6- mercaptopyridines of the formula l d by a method similar to known processes (for example as described in "Methoden der Organischen Chemie" [Methods in Organic Chemistry] (Houben-Weyl), Volume E/b, Heteroarene part 2, Georg Thieme Verlag Stuttgart, 1992, page 286 et seq.) using a suitable sulfur reagent such as, for example, hydrogen sulfide or its alkali metal salt, or thiourea in the presence of an inert solvent and of a base such as, for example, tertiary amines, alkali metal and alkaline earth metal hydroxides, or the corresponding alkali metal or alkaline earth metal oxides. The 6-mercaptopyridine derivative of the formula l d or its alkali metal salt is subsequently reacted with an alkylating reagent of the formula VII in which L is a leaving group, if appropriate in the presence of a base and of a suitable solvent, to give the 6-alkylmercapto derivative of the formula l c . If appropriate, the thioethers of the formula l c (ni =0) can be converted into the sulfoxides or sulfones l c (ni = 1 or 2) by known methods using an oxidant such as, for example, hydrogen peroxide, sodium periodate or m-chloroperbenzoic acid (m-CPBA) in an inert solvent such as, for example, dichloromethane. If appropriate, the reaction may also be stopped at the sulfoxide level. The preparation of the compounds of the formula I in which A, R 1 ( R 2 and W have the meanings given under formula I and R 3 is R 6 O-, R 9 S(O) n ι-, amino, R 4 NH- or R 4 R 5 N- is illustrated in reaction scheme 3 which follows. Reaction scheme 3: IV III VI C) )|| Rn 9g S(0w)7/ 2 j] ' M IVI,, j 0r I (R 3 : R 6 0-, R 9 S(0) -, n ι amino, R 4 NH-, R 4 R 5 N-) XI d) R 4 NH 2 , [R 4 NHJ M*, or NH. or 'exc. II Xlla e) R 4 R 5 NH 2 or [R 4 R 5 NH] M XIII Xllla optional base, solvent The 6-halopyridines of the formula VI can be obtained readily from the corresponding pyridine N-oxides of the formula IV or else from the pyridine derivatives of the formula III in accordance with reaction scheme 3 by known standard methods by means of halogenation, for example using phosphorus oxychloride or phosphorus oxybromide. The reactive 6-halopyridines of the formula VI, in turn, can be reacted either a) with an alcohol of the formula IX, if appropriate in the presence of a base and of an inert solvent, or with the corresponding alkali metal alkoxide of the formula IXa, b) with a thiol of the formula X, if appropriate in the presence of a base and of an inert solvent, or with the corresponding alkali metal thiolate of the formula Xa, c) with an alkali metal sulfinate of the formula XI, or d) and e) with an excess of ammonia, with an amine of the formula XII or XIII, if appropriate in the presence of a base and of an inert solvent, or with the corresponding alkali metal salt of the formula Xlla or Xllla to give the desired compounds of the formula I in which R 3 is either R 6 O-, R 9 S(O) n ι-, amino, R 4 NH- or R 4 R 5 N- by methods similar to known nucleophilic substitution reactions. The 6-mercaptopyridines of the formula I obtained in accordance with variant b) in which R 3 is R 9 S(O) n i and ni is 0 can be converted, if appropriate, by known oxidation methods, for example using hydrogen peroxide, organic peracids, sodium perborate (NaBO 3 ), (NH 4 ) 2 Ce(NO 3 ) 6 , sodium periodate (NalO 4 ) or manganese dioxide (MnO 2 ) to give the compounds of the formula I in which R 3 is RgS(O)„ι- and ni is 1 or 2. Such oxidations are described, for example, in Oxidations in Organic Chemistry", Editor M. Hudlicky, ACS Monograph 186, Washington DC, 1990. The resulting sulfonyl derivatives of the formula I in which R 3 is R 9 S(O) n1 and is 2 can be further derivatized in accordance with the definition of R 3 by known methods, for example by nucleophilic aromatic substitution. The above reactions in accordance with variants a), b), d) and e) are carried out with the non-deprotonated reagents of the formulae IX, X, XII and XIII, preferably in the presence of a base such as, for example, alkali metal hydroxides, alkaline earth metal hydroxides, alkaline earth metal oxides, alkali metal hydrides, e.g. sodium hydride, alkoxides, e.g. potassium tert-butoxide, quaternary ammonium hydroxides or tertiary amines, in a suitable inert solvent. Compounds of the formula I in which R 3 is nitro can be f) either obtained directly by means of nitration and separation of undesired position-isomeric nitro derivatives, g) obtained readily by means of oxidizing the amino group of the corresponding 6-aminopyridine derivative of the formula I (R 3 amino), or) can be obtained by a method similar to what has been described, for example, in "Oxidations in Organic Chemistry", Editor M. Hudlicky, ACS Monograph 186, Washington DC, 1990, from the corresponding pyridine azides (R 3 Λ_Λ_ N ) or from the corresponding amines by oxidation, for example with an alkali metal peroxodisulfate or ammonium peroxodisulfate, for example in concentrated sulfuric acid as solvent at reaction temperatures of from -20° to +30°C. Compounds of the formula I in which R 3 is an amino group (NH 2 ) can furthermore be obtained by rearranging corresponding acetamides (R 3 = -OCH 2 CONH 2 ) in the presence of a base, such as, for example, alkali metal carbonates, in an inert solvent such as, for example, dimethyl sulfoxide at temperatures of from 70° to 150°C. Compounds of the formula I in which R 2 or R 3 is an amino group (NH 2 ) can furthermore also be obtained by reducing the corresponding azides. For example, these azides can be prepared by a Mitsunobu reaction from the hydroxyintermediates, hydrazoic acid (HN 3 ), a phosphine such as, for example, triphenylphosphine and an azo compound such as, for example, diethyl azodicarboxylate in an inert solvent. Such reactions are described, for example, in Synthesis 1992, 367. The other compounds which come under the scope of the formula I can be prepared readily by methods similar to known standard processes taking into consideration the chemical reactivities of the pyridyl moiety and of the pyridyl -(Heterocyclyl)-W moiety (groups Wi to W 4 ). The preparation of the compounds of the formula l e in which R 1 t R 2 , R 3l R 14 , Rι 5 , R 16 , X 3 and X 4 have the meanings given under formula I and R 3 is additionally hydrogen is illustrated in reaction scheme 4 which follows. Reaction scheme 4: thionizing reagent, e.g. Lawesson reagent '15 solvent ι ( 4 s) ι e ( χ 4 O) A multiplicity of known standard processes such as described, for example, in EP-A-0 438 209 and DE-OS-19 604 229 (R 15 cyano) is suitable for the preparation of the compounds of the formula l β according to the invention. Reaction scheme 4 shows a selection of suitable preparation methods, the choice of reaction routes and reagents depending on the reactivities of the substituents at the intermediate levels. For example, starting by reacting a compound of the formula XIV with ammonia in an inert solvent, if appropriate in an autoclave, at temperatures of -10 to 180°C, the aminopyridine of the formula XV can be obtained. The latter can be converted, in the presence of a base and of a solvent, either a) with chloroformic ester of the formula XVI (X 3 oxygen or sulfur) to give a pyridylcarbamate of the formula XVII, or b) with oxalyl chloride, phosgene (X 3 oxygen) or thiophosgene (X 3 sulfur) to give an iso(thio)cyanate of the formula XVIII. Such reactions are described, for example, in Angew. 1971 , 407. The carbamate and the iso(thio)cyanate of the formulae XVII and XVIII can be cyclized in the presence of the enamine derivative of the formula XIX in an inert solvent to give the uracil derivative of the formula XX, the reaction of the iso(thio)cyanate of the formula XVIII advantageously being carried out in the presence of 0.1 -1.5 equivalents of a base such as, for example, sodium hydride, potassium tert-butoxide or alkaline earth metal oxide or alkaline earth metal hydroxide, for example barium hydroxide. The desired compounds of the formula l θ can be obtained by standard processes by converting the uracils of the formula XX in the presence of an inert solvent and at least 1 equivalent of a base, for example alkali metal carbonate, e.g. potassium carbonate, c) with an alkylating agent of the formula XXI to give the N-alkyl derivative of the formula l e (R 14 alkyl), or d) by a method similar to WO 97/05116 with a hydroxylamine derivative of the formula XXII, in which L t is a leaving group, such as, for example, HOS(O) 2 O-, or H 3 C 2 - , for example 2,4-dinitrophenyl- hydroxylamine or hydroxylamine-O-sulfonic acid, to give the N-amino derivative of the formula l e (Rι 4 amino). The thiono derivatives of the formula l θ (X 3 , X sulfur) can be obtained by means of thionation, for example with phosphorus pentasulfide or Lawesson reagent. The preparation of the compounds of the formula I f in which Ri, R 2 , R 3 , Rι ? , Rι 8 , Rι 9 and X 5 have the meanings given under formula I and R 3 is additionally hydrogen is illustrated in reaction scheme 5 which follows. Reaction scheme 5: XIV XXIII y with ngemann The compounds of the formula l f can be prepared by known methods, for example in accordance with reaction scheme 5 by reacting a 2-halopyridine derivative of the formula XIV with hydrazine, preferably in a protic solvent such as, for example, alcohols, by a method similar to GB-A-2 230 261 to give the 2-hydrazino derivative of the formula XXIII. The latter is reacted with a diketone of the formula XXIV by a method similar to DE-OS-19 754 348 or a dihaloketone of the formula XXIVa by a method similar to WO 97/07104 to give the hydrazone derivative of the formula XXV. The subsequent cyclization which yields the desired compound of the formula l f is carried out in the presence of the phosphorane derivative of the formula XXVII, if appropriate in the presence of a base, for example 4-dimethylaminopyridine. In the event that, in the compound of the formula l f , X 5 is O, the product may subsequently be thionized by a method similar to what has been described under reaction scheme 4 (X 5 S). In accordance with reaction scheme 5, the hydrazone derivative of the formula XXV may also be obtained via diazotization, preferably with exclusion of water, and subsequent coupling with the keto acid of the formula XXVI (Japp-Klingemann reaction, similar to DE- OS-19 754 348), starting from the 2-aminopyridine derivative of the formula XV. The preparation of the compounds of the formula l g in which R 1 t R 2 , R 3 , R 2 o, R 2 1, R2 2 , Xβ and X 7 have the meanings given under formula I and R 3 is additionally hydrogen is illustrated in reaction scheme 6 which follows. Reaction scheme 6: Ig (e.g. X- O) thionation, e.g. Lawesson reagent l g (e.g. X 7 S) The compounds of the formula l g can be prepared similarly to known methods such as described, for example, in EP-A-0 272 594, EP-A-0 493 323, DE-A-3 643 748, WO 95/23509, US-A-5 665 681 or US-A-5 661 109. In accordance with reaction scheme 6, for example, either a) a carbamate derivative of the formula XVIIa in the presence of a solvent and of a base or b) an iso(thio)cyanate of the formula XVIIIa, if appropriate in a suitable solvent, may be cyciized with an amino acid derivative of the formula XXVIII via the compound of the formula XXIX in the presence of a base and of a suitable solvent to give the compound of the formula l g . In the event that, in the compound of the formula l g , R 22 is hydrogen and X 6 and/or X 7 are oxygen, the product can, if appropriate, be subsequently alkylated with an alkylating agent of the formula XXX on the free N atom of the hydantoin ring and the ring carbonyl group can be thionated (X 6 and/or X 7 sulfur). In the starting compounds of the formulae XVIIa and XVIIIa in reaction scheme 6, R 3 may also be hydrogen. Functionalization in accordance with the definition of the substituent R 3 in the compounds of the formula l g may then be carried out by processes similar to those given in reaction schemes 1 to 3. The preparation of the compounds of the formula l h in which R 1 ( R 2 , R 3 , R 3 , R 24 , X 8 and X 9 have the meanings given under formula I and R 3 is additionally hydrogen is illustrated in reaction scheme 7 which follows. Reaction scheme 7: l h (e.g. X 9 0) thionation, e.g. Lawesson reagent The compounds of the formula l h can be prepared similarly to known processes such as described, for example, in EP-A-0 210 137, DE-OS-2 526 358, EP-A-0 075 267 or EP-A-0 370 955. In accordance with reaction scheme 7, for example, either a) a carbamate derivative of the formula XVIIb in the presence of a solvent and of a base, or b) an iso(thio)cyanate of the formula XVIIIb, if appropriate in a suitable solvent, may be cyclized with a carbazate of the formula XXXI via the compound of the formula XXXII in the presence of a base and of a suitable solvent to give the compound of the formula l h . In the event that, in the compound of the formula l h , R 2 3 and/or R 24 are hydrogen and X 8 and/or X 9 are oxygen, the product can subsequently be alkylated with an alkylating reagent of the formula XXXIIIa or XXXIIIb on the free N-atoms and the ring carbonyl group can be thionated with the thionating reagent (X 8 and/or X 9 sulfur). To prepare compounds of the formula l h in reaction scheme 7 in which R 23 and R 24 together form an alkylene bridge which is interrupted by, for example, -C(O)- or -S(O) 2 -, for example the compound of the formula l h , in which R 23 and R 2 are hydrogen can be reacted with a suitable Michael acceptor, such as, for example, CH 2 =CH-C(O)CH 3 , CH 2 =CH-S(O) 2 CH 3 or CH 2 =CH-S(O) 2 -CH=CH 2 and the resulting Michael adducts can be functionalized further. The compounds of the formulae l e , I f , l g and l h in the preceding reaction schemes 4 to 7 in which X , X 5 , X 7 and Xg are O and R 3 is hydrogen can subsequently be functionalized, for example as shown in reaction schemes 1 to 3, to give the compounds of the formulae l θ , l ( , l g and l h in which R 3 has the meaning given under formula I. In accordance with reaction scheme 8 which follows, the compounds of the formula I may also be obtained expediently directly by substituting a 2-halopyridine of the formula XIV or XlVa (R 2 = CN) with the desired heterocycles W0 1 to W 04 or salts thereof (for example alkali metal salts), if appropriate in the presence of a suitable solvent and of a base (variant a)). Similar reactions are described, for example, in J. Het. Chem. 15, (1978), 1221. In some cases it may be expedient to couple the heterocyclic group Wi to W 4 , for example as shown in variant b) in reaction scheme 8 with reference to Wi, to the pyridyl moiety by means of direct alkylation with an imino-ether-modified heterocycle of the formula W OOL Reaction scheme 8: Variant a): w Variant b) C C 4 alkyl base, solvent XIV (A =N-) w "°° 1 l (A =N-) L 2 in the compound of the formula XIV in reaction scheme 8 is a leaving group such as, for example, halogen or a C C4alkyl or phenyl-sulfonyl group. The heterocyles of formula W 0 ι in reaction scheme 8 above, wherein Rι is C C 3 alkyl (e.g. methyl), R 15 is Cι-C 3 haloalkyl (e.g. CF 3 ), Rι 6 is hydrogen and X 3 and X 4 are oxygen, are obtained either according to WO 98/08824 or by the reaction sequence as follows: An enamine derivative of formula XXXIV R 27 j ^ (XXXIV) ' wherein Rι 4 is Cι-C 3 alkyl, R i5 is Cι-C 3 haloalkyl and R 7 is Cι-C 4 alkyl, C or C 2 haloalkyl or optionally substituted benzyl, is converted in the presence of chlorocarbonyl isocyanate (CICONCO) in inert organic solvents to the compound of formula XXXV the ester function of which is then transferred to the corresponding carboxylic acid function as represented by compound of formula XXXVI (XXXVI), which then is decarboxylated to yield the compound of formula W 0 ι the radicals R i4 , R i 5 , R 27 , X 3 , X 4 and Rι 6 in the compounds of formulae XXXV, XXXVI and W 0 i having the abovementioned meaning. This reaction sequence is novel and therefore instant invention also relates to this method of preparation. Above reaction sequence is illustrated in reaction scheme 9 which follows. Reaction scheme 9: cleavage by hydrolysis under acid conditions or by enzymatic methods or in presence of an oxidant or by hydrogenolysis (H 2 / cat) XXXVI W 01 (R 16 =H) According to reaction scheme 9 above the enamine derivative of formula XXXIV, wherein Rι 4 and R i5 are as defined and R 27 is d-C alkyl (e.g. t-butyl), C C 2 haloalkyl (e.g. 2,2,2- trichloroethyl) or optionally substituted benzyl (e.g. p-methoxybenzyl) is reacted with chlorocarbonyl isocyanate (CICONCO) in inert sovents such as dichloromethane at temperatures in the range of from -30 C C to +8°C to obtain the pyrimidine derivative of formula XXXV. The carboxylic ester function COOR 27 of compound of formula XXXV is then cleaved for example by hydrolysis or hydrogenolysis to yield the corresponding carboxylic acid function of compound of formula XXXVI according to the following methods as described in 'Protective Groups in Organig Synthesis', Editor Th. Greene, New York, 1981 ; and Houben- Weyl, Band E5, 'Carbonsauren und Carbonsaurederivate', Stuttgart, 1985: treatment with an acid (formic acid containing catalytic amounts of sulfunc acid as described in Houben-Weyl above, p. 227) if R 27 in compound of formula XXXV is alkyl or benzyl; treatment with formic acid, trifluoroacetic acid or HBr if R 27 in compound of formula XXXV is t-butyl or benzyl, treatment with tin (Zn) in acetic acid if R 27 in compound of formula XXXV is 2,2,2- tnchloroethyl, treatment with an oxidant such as ceπc ammonium nitrate in water/acetonitnl if R 2 in compound of formula XXXV is 4-methoxybenzyl, cleavage by hydrogenolysis (H 2 /approprιate catalyst such as Pd-C in inert solvent) if R 27 in compound of formula XXXV is benzyl or substituted benzyl; or by enzymatic cleavage (Ann. Rep. Med. Chem. 19, 263 (1984); Angew. 24, 617 (1985)). Decarboxylation of the carboxylic acid derivative of formula XXXVI to the uracil compound of formula W 0 ι, wherein R 16 is hydrogen is achieved finally by heating net or in inert solvents such as decahne or quinoline with or whithout additional catalysts such as Cu(0) or Cu(l)- salts such as CuCI The compounds of the formulae XIV, XlVa and XV which are not already known can be prepared by known methods such as described in, for example, DE-A-3 917 469; WO 97/07114; WO 92/00976; JP-A-58-213 776; EP-A-0 012 117; EP- A-0 306 547; EP-A-0 030 215; EP-A-0 272 824; EP-A-0 500 209; US-A-4 996 323; US-A-5 017 705; WO 97/05112; J. Het. Chem. 11 (1974), 889; J. Het. Chem 21 (1984), 97, Tetrahedron 41 (1985), 4057; Heterocycles 22,117; Synth. 1988, 938; J Med Chem. 25 (1982), 96, Chem. Pharm. Bull. 35 (1987), 2280 and WO 98/11071. The 2-amιnopyrιdιnes of the formula XV can also be prepared from the corresponding pyridine derivatives which have carboxylic acid, carboxylic acid chloride, carboxylic acid azide, and carboxylic acid ester or carboxamide functions in the 2-posιtιon by Curtius, Hofmann or Lossen degradation reactions The reagents and starting compounds of the formulae V, VII, IX, IXa, X, Xa, XI, XII, Xlla, XIII, Xllla, XVI, XVIIa, XVIIb, XVIIIa, XVIIIb, XIX, XXI, XXII, XXIV, XXIVa, XXVI, XXVII, XXVIII, XXX, XXXI, XXXIIIa, XXXIIIb and XXXIV which have been used in reaction schemes 1 to 9 are either known or can be prepared analogously to known processes. The intermediates of the formulae III and IV in which Ri, R 2 and W have the meanings given under formula I, are novel. The invention thus also relates to these compounds. The intermediates of the formula XVIIb NH-C-OC C 4 alkyl ( XV " b ) in which R 1 t R 2 , R 3 and X 9 have the meanings given under formula I and R 3 is additionally hydrogen are novel. The invention thus also relates to these compounds. The reactions which give compounds of the formula I are advantageously carried out in aprotic, inert organic solvents. Such solvents are hydrocarbons such as benzene, toluene, xylene or cyclohexane, chlorinated hydrocarbons such as dichloromethane, trichloromethane, tetrachloromethane or chlorobenzene, ethers such as diethyl ether, ethylene glycol dimethyl ether, diethylene glycol dimethyl ether, tetrahydrofuran or dioxane, nitriles such as acetonitrile or proprionitrile, amides such as N,N-dimethylformamide, N,N- diethylformamide or N-methylpyrrolidinone. The reaction temperatures are preferably between -20°C and +120°C. In some cases, the reactions are slightly exothermic and, as a rule, they may be carried out at room temperature. To reduce the reaction time, or else to start up the reaction, the reaction mixture may be warmed briefly to boiling point, if appropriate. The reaction times may also be reduced by adding a few drops of base as reaction catalyst. Suitable bases are, in particular, tertiary amines such as trimethylamine, triethylamine, quinuclidine, 1 ,4-diazabicyclo-[2.2.2]-octane, 1 ,5-diazabicyclo-[4.3.0]-non-5- ene, 1 ,5-diazabicyclo-[5.4.0]-undec-7-ene or 4-dimethylaminopyridine. However, inorganic bases such as hydrides, e.g. sodium hydride or calcium hydride, hydroxides such as sodium hydroxide or potassium hydroxide, carbonates such as sodium carbonate or potassium carbonate, or hydrogen carbonates such as potassium hydrogen carbonate and sodium hydrogen carbonate, may also be used as bases. The compounds of the formula I can be isolated in the customary manner by concentrating and/or by evaporating the solvent and purified by recrystallization or trituration of the solid residue in solvents in which they are not readily soluble, such as ethers, aromatic hydrocarbons or chlorinated hydrocarbons, or by means of column chromatography and a suitable eluent. Suitable uses according to the invention of the compounds of the formula I or compositions comprising them are all application methods which are customary in agriculture such as, for example, pre-emergence application, post-emergence application and seed treatment, and a variety of methods and techniques, such as, for example, the controlled release of active ingredient. To this end, the dissolved active ingredient is applied to mineral granule carriers or to polymerized granules (urea/formaldehyde) and dried. If appropriate, an additional coating can be applied (coated granules) which allows controlled release of the active ingredient over a specific period. The compounds of the formula I can be employed as herbicides as pure active ingredients, i.e. as obtained in synthesis. Preferably, however, they are processed in the customary manner with the auxiliaries conventionally used in the art of formulation, for example to give emulsifiable concentrates, directly sprayable or dilutable solutions, dilute emulsions, wettable powders, soluble powders, dusts, granules or microcapsules. Such formulations are described, for example, in WO 97/34485 on pages 9 to 13. The application methods, such as spraying, atomizing, dusting, wetting, scattering or pouring, and the nature of the compositions are chosen to suit the intended aims and prevailing circumstances. The formulations, i.e. the compositions, preparations or combinations which comprise the active ingredient of the formula I or at least one active ingredient of the formula I and, as a rule, one or more solid or liquid formulation auxiliaries, are prepared in the known manner, for example by intimately mixing and/or grinding the active ingredients with the formulation auxiliaries such as, for example, solvents or solid carriers. Furthermore, surface-active compounds (surfactants) may additionally be used when preparing the formulations. Examples of solvents and solid carriers are given, for example, in WO 97/34485 on page 6. Suitable surface-active compounds are, depending on the nature of the active ingredient of the formula I to be formulated, non-ionic, cationic and/or anionic surfactants and surfactant mixtures which have good emulsifying, dispersing and wetting properties. Examples of suitable anionic, non-anionic and cationic surfactants are listed, for example, in WO 97/34485 on pages 7 and 8. The surfactants conventionally used in the art of formulation described in, inter alia, "McCutcheon's Detergents and Emulsifiers Annual" MC Publishing Corp., Ridgewood New Jersey, 1981 , Stache, H., "Tensid-Taschenbuch" [Surfactants Guide], Carl Hanser Verlag, Munich/Vienna, 1981 , and M. and J. Ash, "Encyclopedia of Surfactants", Vol Mil, Chemical Publishing Co., New York, 1980-81 are furthermore also suitable for preparing the herbicidal compositions according to the invention. As a rule, the herbicidal formulations comprise 0.1 to 99% by weight, in particular 0.1 to 95% by weight, of herbicide, 1 to 99.9% by weight, in particular 5 to 99.8% by weight, of a solid or liquid formulation auxiliary and 0 to 25% by weight, in particular 0.1 to 25% by weight, of a surfactant. While concentrated compositions are more preferred as commercially available goods, the end user uses, as a rule, dilute compositions. The compositions may also comprise other additives such as stabilizers, e.g. epoxidized or unepoxidized vegetable oils (epoxidized coconut oil, rapeseed oil or soya oil), antifoams, e.g. silicone oil, preservatives, viscosity regulators, binders, tackifiers and fertilizers or other active ingredients. As a rule, the active ingredients of the formula I are applied to the plant or its environment at application rates of 0.001 to 4 kg/ha, in particular 0.005 to 2 kg/ha. The dosage required for the desired action can be determined by experiments. It depends on the type of action, the developmental stage of the crop plant and of the weed, and on the application (location, timing, method) and, due to these parameters, may vary within wide ranges. The compounds of the formula I are distinguished by herbicidal and growth-inhibitory properties which allow them to be used in crops of useful plants, in particular in cereals, cotton, soya, sugar beet, sugar cane, plantation crops, oilseed rape, maize and rice and for non-selective weed control. Crops are also to be understood as meaning those which have been made tolerant to herbicides, or classes of herbicides, by conventional breeding or genetic engineering methods. The weeds to be controlled may be monocotyledonous or dicotyledonous weeds such as, for example, Steliaria, Nasturtium, Agrostis, Digitaria, Avena, Setaria, Sinapis, Lolium, Solanum, Echinochloa, Scirpus, Monochoria, Sagittaria, Bromus, Alopecurus, Sorghum halepense, Rottboellia, Cyperus, Abutilon, Sida, Xanthium, Amaranthus, Chenopodium, Ipomoea, Chrysanthemum, Galium, Viola and Veronica. The examples which follow illustrate the invention in greater detail without imposing any limitation. Preparation examples: Example H1 : Preparation of 2-N-ethoxicarbonylamino-3-fluoro-5-chloropyridine 294 g of 2-amino-3-fluoro-5-chloropyridine are dissolved in 1 I of dry pyridine, the solution is cooled to 0°C, 220 g of ethyl chloroformate are added dropwise with stirring, and the mixture is stirred at 22°C until the reaction is complete. The reaction mixture is then poured into ice-water, brought to pH 4-5 using 2N hydrochloric acid and extracted with ethyl acetate. The combined extracts are washed with water, dried over sodium sulfate, evaporated and crystallized by adding n-hexane. The resulting precipitate is filtered off, washed with n-hexane and dried in vacuo. This gives the desired title compound of m.p. 132°C. Example H2: Preparation of 1 -(3-fluoro-5-chloropyridine-2-yl)-3-methyl-4-trifluoromethyl- pyrimidine-2,6-dione (compd. no. 600.001) A solution of 22.7 g of ethyl 4,4,4-trifluoro-3-amino-2-butenoate is added dropwise with stirring and cooling at 0-5°C under a nitrogen atmosphere to 5.1 g of a previously introduced sodium hydride dispersion (60%) in 60 ml of n-methylpyrrolidine, and stirring is continued at 22°C until the evolution of hydrogen has ceased. Then, 23.7 g of 2- ethoxycarbonylamino-3-fiuoro-5-chloropyridine (Example H1 ) are added and the reaction mixture is heated for approx. 5 hours at 120°C. It is then cooled, 16.7 g of methyl iodide are added dropwise, and stirring is continued overnight at 22°C. After the reaction mixture has been taken up in ethyl acetate, it is washed with ice-water, dried over sodium sulfate, filtered and evaporated. The residue obtained is recrystallized from ethyl acetate/n-hexane. This gives the desired title compound of m.p. 133-134°C. Example H3: Preparation of 1-(3-fluoro-5-chloro-2-pyridyl-N-oxide)-3-methyl-4- trifluoromethyl-pyrimidine-2,6-dione (compd. no. 617.001 ) 24 g of 1 -(3-f luoro-5-chloropyridine-2-yl)-3-methyl-4-trifluoromethylpyrimidine-2,6-dione (Example H2) in 150 ml of dichloromethane is cooled to -5°C and treated with 2 g of hydrogen peroxide/urea adduct. 2.7 ml of trifluoroacetic anhydride, dissolved in 2 ml of dichloromethane, are subsequently metered in and, when the exothermal reaction has subsided, the reaction mixture is stirred overnight. Then, again, 3 ml of trifluoroacetic anhydride and 5 g of hydrogen peroxide/urea adduct are added in two portions in the course of 3 hours and, when the exothermal reaction has subsided, the reaction mixture is heated at 25-35°C until the reaction is complete. It is subsequently cooled and, at -5°C, brought to pH 7.5, first with 2 N sodium hydroxide solution and then with saturated sodium hydrogen carbonate solution, the mixture is partitioned between dichloromethane and icewater, and the organic phase which has been separated off is dried over sodium sulfate, filtered and concentrated by evaporation. The solid residue which remains is recrystallized from ethyl acetate/n-hexane. This gives the desired product of m.p. 142-143°C. Example H4: Preparation of 1-(3-fluoro-5,6-dichloro-2-pyridyl)-3-methyl-4-trifluoromethyl- pyrimidine-2,6-dione (compd. no. 1.396) A solution of 2.4 ml of phosphorus oxytrichloride in 20 ml of 1 ,2-dichloroethane, heated at 70°C, is treated with 6.8 g of 1 -(3-fluoro-5-chloro-2-pyridyl-N-oxide)-3-methyl-4- trifluoromethyl-pyrimidine-2,6-dione (Example H3), a little at a time, and kept overnight at this temperature, a further 4.0 ml of phosphorus oxytrichloride are added, and the mixture is heated for a further 20 hours. It is subsequently cooled, poured into ice-water and extracted with dichloroethane, and the combined extracts are washed with ice-cooled 2N sodium hydroxide solution and water, dried over sodium sulfate and concentrated by evaporation. The residue is purified by silica gel chromatography (eluent: hexane/ethyl acetate 9/1). This gives the desired title compound of m.p. 113-115°C. Example H5: Preparation of 1 -(2-hvdroxy-3-chloro-5-fluoropyridine-6-yl)-3-methyl-4- trif luoromethylpyrimidine-2,6-dione and 1 -(3-hydroxy-2-chloro-5-f luoropyridine-6-yl)-3- methyl-4-trifluoromethylpyrimidine-2,6-dione A solution of 29.6 g of 1 -(3-fluoro-5-chloro-2-pyridyl-N-oxide)-3-methyl-4-trifluoromethyl- pyrimidine-2,6-dione (Example H3) in 400 ml of dimethylformamide, cooled to -30°C, is treated dropwise with 182 g of trifluoroacetic anhydride, stirred overnight at -30°C and the next day at 22°C. Then, the mixture is freed from excess trifluoroacetic anhydride in vacuo, cooled to -5°C and carefully neutralized, first with dilute sodium hydroxide solution and then with sodium hydrogen carbonate solution. After addition of ice-water, the mixture is extracted with ethyl acetate, and the combined extracts are washed with water and dried over sodium sulfate. The mixture is then filtered, the filtrate is concentrated by evaporation and the residue obtained is purified over a silica gel column (eluent: n-hexane/ethyl acetate 8/2, increasing ethyl acetate gradient). This gives the desired title compound (compd. no. 1.002) of m.p. 200-202°C. Besides that, a mixed fraction is obtained which, in addition to 1-(2-hydroxy-3-chloro-5- fluoro-pyridine-6-yl)-3-methyl-4-trifluoromethylpyrimidine-2,6-dione, furthermore also contains the isomer 1 -(3-hydroxy-2-chloro-5-fluoropyridine-6-yl)-3-methyl-4- trifluoromethylpyrimidine-2,6-dione. The latter isomeric compound is obtained by a further rearrangement. The ratio of the two isomers 1 -(2-hydroxy-3-chloro-5-f luoropyridine-6-yl)-3- methyl-4-trif luoromethylpyrimidine-2,6-dione and 1 -(3-hydroxy-2-chloro-5-fluoropyridine-6- yl)-3-methyl-4-trifluoromethypyrimidine-2,6-dione varies, depending on the reaction conditions (approx. 3:1 ). The isomer mixture of the mixed fraction can either be used directly in the next reaction step or separated by means of HPLC (Li-Chrospher Si60; eluent: ethyl acetate/hexane 15/85 to 30/70, increasing ethyl acetate gradient). This gives pure 1 -(3-hydroxy-2-chloro-5- fluoropyridine-6-yl)-3-methyl-4-trifluoromethylpyrimidine-2,6-dione of m.p. 189-192°C. Example H6: Preparation of 1 -(2-proparqyloxy-3-chloro-5-fluoropyridine-6-yl)-3-methyl-4- trifluoromethylpyrimidine-2,6-dione. 1-(2-chloro-3-proparqyloxy-5-fluoropyridine-6-yl)-3- methyl-4-trif luoromethylpyrimidine-2.6-dione and 1 -(1 -proparqyloxy-3-chloro-5-f luoro-2- pyridon-6-yl)-3-methyl-4-trifluoromethylpyrimidine-2,6-dione and A suspension of 10.2 g of a mixture of 1-(2-hydroxy-3-chloro-5-fluoropyridine-6-yl)-3-methyl- 4-trifluoromethylpyrimidine-2,6-dione and 1 -(2-chloro-3-hydroxy-5-f luoropyridine-6-yl)-3- methyl-4-trifluoromethylpyrimidine-2,6-dione (Example H5), 7.5 g of potassium carbonate and 0.08 g of 18-crown-6 in 180 ml of acetonitrile is treated dropwise with 4.5 ml of propargyl bromide and subsequently heated overnight at 65 °C. The mixture is then concentrated by evaporation in vacuo, the residue obtained is treated with ethyl acetate/ice- water mixture and 1 N hydrochloric acid until the pH is 7, the aqueous phase is separated off and extracted with ethyl acetate, and the combined organic phases are washed with water, dried over sodium sulfate and filtered, and the filtrate is concentrated by evaporation. The residue is purified by means of silica gel chromatography (eluent: n-hexane/ethyl acetate 8/2). This gives the desired isomers 1-(2-propargyloxy-3-chloro-5-fluoropyridine-6- yl)-3-methyl-4-trifluoromethylpyrimidine-2,6-dione, m.p. 121-122°C (compd.no.1.022), 1-(2- chloro-3-propargyloxy-5-fluoropyridine-6-yl)-3-methyl-4-trifluoromethyl-pyrimidine-2,6-dione, m.p. 69-71 °C and 1-(1-propargyloxy-3-chloro-5-fluoro-2-pyridon-6-yl)-3-methyl-4- trifluoromethylpyrimidine-2,6-dione, m.p. 223-224°C. Example H7: Preparation of tetrahvdroimidazof 1.5-a]pyridine-1 ,3-dione 34.6 g (0.193 mol) of methyl 2-piperidinecarboxylate hydrochloride are introduced into 260 ml of water in a reaction vessel and 17.4 g (0.216 mol) of potassium cyanate are added. 30 ml of glacial acetic acid are then added, and the homogenous solution formed is stirred for 4.5 hours at 22°C. The reaction solution is subsequently saturated with sodium chloride (NaCl) and extracted twice using in each case 200 ml of tert-butyl methyl ether. The organic fractions are combined, dried over sodium sulfate and concentrated. 11 g of a viscous oil, from which crystals separate out overnight, is obtained as residue. The crystals are separated off by decanting off the remaining oil and purified by triturating (digesting) with diethyl ether. This gives the desired product of m.p. 122-123°C in a yield of 5.75 g. Example H8: Preparation of 2-(3-fluoro-6-chloro-5-cyano-2-pyridyl)tetrahydroimidazo[1.5- alpyridine-1 .3-dione (compd. no. 81.396) 0.77 g (0.005 mol) of the hydantoin derivative of Example H7 is introduced into 50 ml of acetonitrile in a reaction vessel. This solution is treated in succession with 0.95 g (0.00688 mol) of finely pulverulent potassium carbonate and 0.96 g (0.00503 mol) of 2,6- dichloro-3-cyano-4-fluoropyridine and heated for 5 hours to reflux temperature, with stirring. After this time, starting material can no longer be detected (TLC analysis). The reaction mixture is cooled and filtered, and the solvent is evaporated. The resulting dark brown viscous oil is chromatographed over a silica gel column (30 g) under pressure (eluent: hexane/ethyl acetate 2/1 ). The product-containing fractions which have an R ( value 0.26 are combined and freed from solvent. This gives the desired product as white crystals of m.p. 192-193°C. MS (FD): [M\ 40%] 308. Example H9: Preparation of 2-(3-fluoro-5-cvano-6-methoxy-2-pyridyl)tetrahvdroimidazof1.5- a]pyridine-1 ,3-dione O F N- / x / W . -CN (compd. no. 81.016) O OCH 3 0.85 g (0.00275 mol) of the compound of Example H8 is dissolved in 50 ml of dry acetonitrile and 0.56 ml (0.003 mol) of sodium methoxide (5.4 molar in methanol) is added. This reaction mixture is heated to boiling point and kept at reflux temperature for 2.5 hours. During this process, the reaction mixture slowly turns cloudy and a solid precipitate separates out. According to TLC analysis, less than 10% starting material is still present. After the reaction mixture has been cooled, filtered and concentrated, 0.8 g of a viscous oil remains, and this is treated with 50 ml of water and extracted twice using in each case 50 ml of dichloromethane. The combined organic phases are dried over sodium sulfate and concentrated, and the residue obtained is digested in diethyl ether. This gives the desired target compound as pale yellow crystals of m.p. 159-170°C.
