Conventionally, aspirin, phenylbutacin, and the like have been known as anti-inflammatory, analgesic, and antipyretic agents, but recently, indomethacin, diclofenac sodium, and the like, which have excellent anti-inflammatory effects, have been frequently used. However, these drugs have drawbacks such as severe side effects such as toxicity and gastric disorders, and lack of long-lasting effects. So, a new type with improved properties?

Preparation of the compounds of the invention can be accomplished by several methods. For example, esters represented by the general formula (2) (wherein R represents a lower alkyl group having 1 to 4 carbon atoms) and esters represented by the general formula (3) (wherein, X represents a halogen atom) Obtained by condensation reaction with aminopyridines. This reaction can be carried out by heating both components in an inert, high boiling solvent such as xylene. In this case, the adone component is usually used in a stoichiometric excess amount relative to the ester component, and the reaction temperature is 100°C.
As mentioned above, it is advantageous to use a temperature as high as possible up to the boiling point of the solvent used. Reaction times range from 4 to 30 hours, usually from 8 to 20 hours. In addition, the product is generally produced by crystallizing the reaction solution as it is or by cooling it after distilling off a portion of the solvent, separating it by a method such as Sawabetsu, and then washing it.
It can be recrystallized and purified.

It is not practical as it involves a long reaction time.

Therefore, in carrying out the present invention, the compound represented by formula I is used as a starting material, which is once diazotized by a conventional method, and then reacted with a mixture of acetic acid water containing sulfur dioxide and cupric chloride. The compound of formula (2) can be obtained by pouring the resulting reaction mixture into ice water to precipitate. In this case, since the diazotide is not isolated, the reaction can be substantially carried out in one step and the yield is also excellent. The subsequent reactions from the chlorsulfonylthiophene 1 thus obtained are often utilized in the synthesis of oxicam anti-inflammatory agents.

The ability of the compounds of the present invention to inhibit carrageenan edema, that is, the potency of the action against acute inflammation, is between the conventional anti-inflammatory agents indomethacin and diclozenaf sodium and the new type of compound-H, which has strong anti-inflammatory activity. However, the dose that causes gastric disorder is higher than any of the comparative drugs, especially more than 10 times that of Compound-H. Therefore, the difference in therapeutic coefficient appears to be 6 to 9 times. It also has low acute toxicity.

On the other hand, Compound-H, the control, has a safety margin close to the same level as Compound-Ct and Compound-F, but its therapeutic coefficient is comparable to that of conventional anti-inflammatory drugs, and it has side effects that are particularly important for anti-inflammatory drugs. The drawback is that gastric disorders occur at very low doses.
