[Step (Π)] In the step (ii), the compound of the formula (III) is first reacted with the compound of the formula (IV), followed by an enaminelation step. The structure of the compound of the formula (IV) wherein R2 and R3 are appropriately selected depending on the structure of the compound of the formula (I) according to the object of the formula (I). Further, R5 represents a Ci.4 alkyl group, and a methyl group or an ethyl group is preferred. Specific examples of the compound of the formula (IV) are, for example, methyl 2-methylacetamacetate, ethyl 2-methylacetate acetate, ethyl 2-benzylacetate, ethyl 2-ethylacetate, Examples of ethyl 2-isopropylacetate, ethyl 2-allylacetate, and the like. The amount of the α-alkyl-β-ketoester represented by the formula (IV) can be appropriately selected depending on the reaction conditions and the like, and is usually preferably 0.8 to 2.0 equivalents, more preferably 1.0 to 1.5 equivalents, and most preferably For the -12-(9) (9)1320782 1.2~1.3 equivalents, the reaction is carried out in the presence of an acidic catalyst or a salt-based catalyst, and an acidic catalyst is preferred. Examples of the acid catalyst include a protonic acid such as acetic acid, trifluoroacetic acid or p-toluenesulfonic acid, and a Lewis acid such as a boron trifluoride diethyl ether complex, and those which are thiol-based catalysts such as hexahydropyridine. When hexahydropyridine is used, it is preferred to use an ethanol solvent, but the reaction time is relatively time consuming compared to an acidic catalyst. This enamine can be carried out without a solvent, and is generally carried out in an inactive solvent which is made into an azeotropic mixture with water such as toluene, xylene or ethanol. After heating at 100 ° C to 140 ° C, it is preferred to promote the removal of the formed water by azeotropic action. Further, in order to effectively remove the water generated by the lapse of time, a Dean and Stark yin is placed in the reaction apparatus: a device, a molecular sieve, and the like, and a suitable dehydrating agent is used to form a reaction container capable of effectively removing water. Suitable. When the reaction is carried out using toluene as a solvent, it is carried out under reflux conditions for 2 hours to 5 hours while stirring. The progress of the reaction is observed by observing the residual ratio of the starting 4-alkyl-2-fluoroaniline derivative by high-speed liquid chromatography or the like. This reaction is an equilibrium reaction in which the starting material is not completely disappeared, and it is preferred to stop the reaction when the reduction of the 4-alkyl-2-fluoroaniline derivative is stopped a little. The prolongation of time not only causes an adverse reaction such as re-decomposition of the produced (V) alkene, but also causes a decrease in yield. Further, the obtained enamine compound is unstable, and the tannin extract rapidly decomposes, so that it is difficult to separate in the gelatin chromatography. In the case of refining, it is preferred to carry out the separation by distillation. Usually, without detachment, the following cyclization anti-13-1320782 do) should be used. An ideal precaution of the present invention is to carry out the cyclization reaction after the residual starting material 4-alkyl-2-fluoroaniline, and the formula (VI) of the tautomer of formula (I) (only, r4 = h) is formed. When the ketone moiety at the 4-position of the quinolinol body reacts with the amine group of the 4th keto-2-fluoroaniline, a by-product is formed, which may drastically reduce the yield. Therefore, in the preferred embodiment of the present invention, after the amination reaction is completed, the liquidity of the reaction liquid is added to a salt group such as hexahydropyridine or triethylamine to form a salt-based stability, and then anhydrous acetic acid and chloride B are added. After the acetalization agent such as an oxime ester, the acetylation of the amine group of the 4-alkyl-2-fluoroaniline is carried out, and the formation of by-products is suppressed after the nucleation of the amine group is suppressed. The protection of the amine group is not limited to the ethyl hydrazide group, and it may be generally protected by a urethane type protecting group such as a guanamine type protecting group such as trimethyl acetyl hydrazine, a benzyloxycarbonyl group or a tert-butoxycarbonyl group. It. In the step (ii), the cyclization reaction of the compound of the formula (V) is carried out by heating. The reaction is carried out at a reflux temperature of the solvent while heating in a suitable solvent. Preferred solvents are, for example, diphenyl ether, xylene, polyphosphoric acid, dark coal, biphenyl, dimethylformamide, and dimethyl sulfoxide. In a preferred embodiment of the present invention, after the enamine reaction is continued in a single tank for cyclization, diphenyl ether is added to the enamine reaction solution to distill off toluene while heating to 250 ° C of the boiling point of diphenyl ether. It. This reaction is based on the fact that the new diene of the α,β·unsaturated carbonyl moiety of the enamine and the benzene nucleus are found to be multi-centered by heat in the molecule, which is synthesized by the so-called Conrad-Linbach Responder. This reaction can also be carried out in a xylene solvent under reflux conditions of -14-(11) 1320782 140 °c. Further, according to WO 00/475 77, after the polyphosphoric acid is used as a solvent, the mixture is heated to 160 ° C, and once the enaminerization-cyclization reaction is initiated once, the formula (I) can also be obtained (only, R4 = H) Quinolinol body. The compound of the formula (I) (here, R4 = H) is a tautomer, and the following formula (VI) may also be present. 0
