Particularly, some of these compounds show extremely high selectivity to sugar beets. Conventionally, a number of compounds having sulfonylurea structure have been known. Any of these, however, show very strong activities to sugar beets. For example, sugar beets have extremely high sensibility to chlorsulfuron which is known as a herbicide for wheat, and accordingly the sugar beets which are cultured as second crops after wheat are known to be seriously suffered from damages by the agricultural chemicals even after two years, because of a trace amount of the active component remaining in the soil. Also, other sulfonylurea compounds than the chlorsulfuron are also considered to have very particularly strong effect on sugar beets, and, of the sulfonylurea type compounds, almost no compound which may have the selectivity to sugar beets have been hitherto unknown. Also, certain compounds of the compounds of this invention have the selectivity not only to beets but also to rice plants, wheat, cotton, corn, etc. The compound of this invention, on the other hand, shows a high herbicidal activity in an application of a very low amount of the active component as compared with the conventional herbicides, and accordingly it is useful also as a herbicide for orchards and uncultivated lands. As a prior technique, European Patent Publication No. 87,780 discloses a pyrazolesulfonylurea which has the structure similar to the compound of this invention. However, there has been nothing disclosing the compound wherein a fused heterocyclic ring is substituted on a pyrazole ring as the comopound of this invention. Thus, the compound of this invention can be said to be a novel one. DESCRIPTION OF THE PREFERRED EMBODIMENTS The compound of this invention, represented by Formula (I) can be readily prepared by selecting any of reaction schemes l to 3 shown below.

Namely, the pyrazolesulfonyl(thio)isocyanate derivative (II) is dissolved in a sufficiently dried inert solvent such as dioxane and acetonitrile and thereto is added a pyrimidine, triazine or triazole derivative represented by Formula (III), with stirring. Thus, the reactants generally are reacted with each other rapidly to give the compound (I)′ which is a part of the compound of this invention. In cases where it is difficult for the reaction to proceed, a trace or small amount of a suitable base, such as triethylamine, triethylenediamine, pyridine, a sodium alkoxide, sodium hydride and the like, may be added to the reaction system to allow the reaction to proceed readily.

Namely, the pyrazolesulfonamide derivative (V) is reacted with a chloroformic acid (thio)ester or a carbonic acid (thio)ester in such a solvent as acetone, methyl ethyl ketone and acetonitrile in the presence of a base such as potassium carbonate to give the compound (IV). Then, the resulting compound (IV) is heated with the compound (III) in such a solvent as toluene to give the compound (I)′ which is a part of the compound of this invention.

The starting materials, the pyrazolesulfonyl (thio)isocyanate (II) and the pyrazolesulfonyl (thio)carbamate derivatives (IV) which is used in Reaction Schemes l and 2 may be synthesized by selecting appropriately the methods as will be described hereinafter to synthesize the pyrazolesulfonamide (V) and further it can be led to a final product with reference to the methods as described in Published European Patent Application No. 87,780 and Japanese Unexamined Patent Publication No. 13266/1980. The pyrazolesulfonamide which is an intermediate compound to be used in the present invention is also a novel compound, which can be obtained by selecting appropriately one of the following Reaction schemes 4 to 8. Reaction scheme 4 Reaction scheme 5 Reaction scheme 6 Reaction scheme 7 Reaction scheme 8 Reaction sheme 9 (a) NaNO₂ · HCl or NaNO₂ · HBr (b) SO₂ · Cu salt (c) NH₄OH or ammonium carbonate (d) Cu salt (e) POCl₁₃ or POBr₃ (f) P₂S₅ (g) NaSH (h) NaOH · NH₄ OH · NaOCl (i) NaSCH₂Ph (j) Cl₂/CH₃COOH · H₂O or NaOCl/HCl (k) BuLi or LiN(i-Pr)₂ subsequently, Cl₂ or Br₂ (l) Oxidizing agent (m) l) ClSO₃H [ 2)SOCl₂ or PCl₅] (n) l) BuLi or LiN(i-Pr)₂ 2) SO₂ 3) N-chlorosuccinimide ClC(=S)NMe₂/base (p) heating (q) RHal/base wherein B, D, Q and E, have the same meanings as defined above; R represents a C₁-C₈ alkyl group, a C₁-C₈ alkenyl group, a C₁-C₈ alkynyl group, a group, of -CH₂CN, a C₁-C₈ alkoxy-C₁-C₈ alkyl group, a C₁-C₈ alkylthio-C₁-C₈ alkyl group, a group of -CH₂COOR-¹³ a group of -COR¹³, a group of -SO₂R²⁴ or a group of-SO₂NR¹³R²⁴; and R¹³ and R²⁴ have the same meanings as defined above. The pyrazolesulfonamide (V) may usually be obtained by reacting a corresponding pyrazolesulfonyl chloride with an aqueous ammonia or ammonium carbonate. In order to introduce a sulfonyl group into a pyrazole, there may be adopted such a method as follows: (l) The amino group is subjected to diazonium decomposition in the presence of sulfur dioxide to give a pyrazolesulfonyl chloride; (2) A hydroxypyrazole is converted into an O-pyrazole thiocarbamate, which is then subjected to rearrangement reaction to introduce a sulfur atom in the pyrazole ring followed by oxidation to give a pyrazolesulfonyl chloride; (3) A sulfur atom is introduced in the pyrazole ring by a nucleophilic substitution reaction with a halogen atom or the like and optionally the resulting compound is further oxidized to give a pyrazolesulfonyl chloride; (4) A carbanion of a pyrazole is formed by using a base and the sulfur dioxide is reacted therewith followed by halogenation to give a pyrazolesulfonyl chloride; (5) Chlorosulfonic acid or the like is directly used to give a pyrazolesulfonyl chloride; (6) The pyrazole derivative, which has been obtained by any of the above-mentioned methods, is functionally modified by utilizing the properties of the pyrazole. Namely, (l) according to Reaction scheme 4, an aminopyrazole is converted into a diazonium salt by using sodium nitrite or the like in hydrochloric acid, hydrobromic acid or the like and then sulfur dioxide is reacted with the resulting diazonium salt in the presence of a catalyst which is used usually for diazonium decomposition such as a copper salt or the like, to afford a corresponding pyrazolesulfonyl chloride. With the resulting compound was reacted an aqueous ammonia to give the desired pyrazolesulfonamide (V). (2) According to Reaction scheme 8, starting from a hydroxypyrazole, an O-pyrazole thiocarbamate is obtained and then the resulting compound is rearranged under heating to give an S-pyrazole thiolcarbamate which is then oxidized with chlorine in such a solvent as acetic acid to afford a pyrazolesulfonyl chloride. As in Reaction scheme 4, action of an aqueous ammonia gives the desired pyrazolesulfonamide (V). Be noted that these Reaction schemes 4 and 8 may be applied without any dependency upon the position(s) of the substituent(s). (3) In the nucleophilic substitution reaction on the pyrazole, the 5 position on the pyrazole ring is usually reacted most easily, but there may be a case where the nucleophilic substitution reaction further occurs at the 3 position when an electron attracting group is substituted at the 4 position. By using this property, according to Reaction scheme 5, a pyrazole halogenated at the 5 position is treated with sodium sulfide, sodium salt of benzylmercaptan or the like to introduce a sulfur atom into the 5 position followed by oxidation with chlorine in such a solvent as acetic acid to give a pyrazolesulfonyl chloride. As in Reaction scheme 4, a reaction with an aqueous ammonia gives the desired pyrazolesulfonamide (V). The desired pyrazolesulfonamide may also be obtained by converting the intermediate 5-mercaptopyrazole into a sulfenamide which is then oxidized. The starting material, the pyrazole halogenated at the 5 position, may be obtained by diazo-decomposition of an aminopyrazole; by the reaction of a hydroxypyrazole with phosphorus oxychloride or phosphorus oxybromide; or by formation of an anion at the 5 position by using such a strong base as butyl lithium, lithium diisopropylamide or the like, followed by halogenation. (4) In cases where there is a substituent at the l position, the hydrogen atom at the 5 position on the pyrazole ring has a relatively strong acidity. According to Reaction scheme 7, an anion may be formed by using such a strong base as butyl lithium, lithium diisopropylamide or the like, and the resulting anion may further be treated by sulfur dioxide and subsequently with an N-halogenosuccinimide to form a pyrazolesulfonyl chloride which is then treated with an aqueous ammonia to give the pyrazolesulfonamide (V). (5) As compared with the nucleophilic substitution reaction, the electrophilic substitution reaction on the pyrazole ring may usually occur more easily at the 4 position. According to Reaction scheme 6, use of chlorosulfonic acid may give directly a pyrazolesulfonyl chloride. (6) According to Reaction scheme 9, when a pyrazolesulfonamide having no substituent on the l position is subjected to alkylation, acylation or sulfonylation, the l or 2 position may be alkylated, acylated or sulfonylated, respectively. According to this method, there may be obtained, depending upon the starting material used, a mixture of two kinds of compounds in which substituents on the 3 and 5 positions have been switched with each other. However, these compounds may be separated by recrystallization, column chromatography or the like and used as an intermediate compound for the compound of this invention. Further, various kinds of pyrazolesulfonamide (V) may be obtained by newly introducing a substituent in the pyrazolesulfonamide or by modifying the introduced substituent, utilizing the properties of a pyrazole. As to the synthesis of pyrazolesulfonamide in which a hetero ring is substituted on the pyrazole ring, specifications of Japanese Patent Application No. 78784/l985 and No. 236780/l985 can be referred to The pyrazoles used as starting materials in the abovementioned reactions may be synthesized in many cases with reference to A.
