This invention relates to a method for producing 1,5-benzothiazepine derivatives. According to the present invention, as shown below, 1.5-
A benzothiazepine derivative is obtained. That is, [In the formula, R 1 is a hydrogen atom or an acetyl group, R 2 is a hydrogen atom or a β-dimethylaminoethyl group,
represents a halogen atom] Here, the reaction proceeds by heating the compound represented by formula () in an appropriate solvent in the presence of copper powder or a copper compound and a base. The compound represented by formula () is a new compound, and this reaction is new as a method for synthesizing this type of fused ring compound. As X in the compound represented by formula (),
Cl, Br, I, and copper compounds include copper oxide,
Examples include inorganic compounds such as cuprous chloride, cuprous bromide, cuprous iodide, cupric chloride, cupric bromide, copper carbonate, and copper hydroxide, and organic compounds such as copper acetate and copper EDTA. It will be done. Further, any solvent may be used as long as it does not participate in the reaction, but preferred solvents include dimethylformamide, dimethylsulfoxide, hexamethylphosphoramide, N-ethyl-2-pyrrolidone, and amyl alcohol. Furthermore, mixtures of these with aromatic solvents such as benzene, toluene, xylene, or halogenated compounds thereof can also be used. Examples of the base used here include inorganic bases such as sodium carbonate and potassium carbonate, and organic bases such as triethylamine and N-methylmorpholine. The compound () used in the present invention is (
a) and (b), and can be synthesized, for example, as follows. [In the formula, X represents a halogen atom, R 2 represents a hydrogen atom or a β-dimethylaminoethyl group, and R 3 represents a lower alkyl group] (1) o-halogenothiophenol and p-methoxyphenyl glycide ester The reaction is carried out without a solvent or in an appropriate solvent. (2) The obtained compound () is hydrolyzed with a dilute alkaline aqueous solution to obtain the compound (). (3) Compound () is obtained by acetylating the obtained compound (). (4) Compound () is reacted with ammonia or β-dimethylaminoethylamine in the presence of a condensing agent or converted into a reactive derivative of carboxylic acid to obtain compound (b). (5) Compound () is reacted with ammonia or β-dimethylaminoethylamine in the presence of a carbodiimide condensing agent (e.g. DCC) to form compound (
obtain a). (6) Compound (b) is hydrolyzed to form compound (
obtain a). Alternatively, compound (b) can be obtained by acetylating compound (a). According to the invention, when preparing 1,5-benzothiazepine derivatives, especially N-substituted derivatives, alkali metal compounds used in the prior art, such as sodium, potassium, sodium hydride, potassium hydride, sodium amide Since dangerous metal compounds such as potassium amide and the like are not used, there is an advantage that dangers in industrial manufacturing sites that cannot be avoided with conventional techniques can be avoided. The compounds obtained by the present invention are useful as therapeutic agents for cardiac diseases. In addition, in the description of this specification, the expression "erythro" used in determining the steric configuration of a compound is based on the projection projection method of Fischer.
This is a representation for a compound with the structure illustrated below.

Examples will be shown below to specifically describe the present invention. Example 1 Erythro-2-hydroxy-3-(p-methoxyphenyl)-3-(o-iodophenylthio)-
351.6 mg of propionic acid amide was added to 5 ml of dimethylformamide and 5 ml of benzene, and the mixture was heated and stirred using a Dern-Stark apparatus to an internal temperature of 110°C. 15.5 mg of copper iodide and 124.5 mg of potassium carbonate were added, and the mixture was further heated and stirred for 2 hours. The solvent was distilled off under reduced pressure, and chloroform was added to the residue. The chloroform layer was washed with water, dried, concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (eluted with benzene:ethyl acetate = 8:2) and recrystallized from benzene to give cis-3-hydroxy-2-(p-methoxy).
