Definitions
- PROCESS FOR THE PREPARATION OF N-METHYL PYRIDYL-3.-2 T ⁇ TRAHYDROTHIOPYRANNECARBOTHIOAMIDE-2-OXIDE- 1 -O R.2R
- the present invention relates to a process for the preparation of N-methyl (3-pyridyl) -2 tetrahydrothiopyrannecarbothioamide-2-oxide-1- (1R, 2R) of formula:
- R represents a hydrogen atom or an alkyl radical containing 1 to 4 carbon atoms
- Het represents a heterocyclic radical of aromatic character
- Y represents a valence bond or a methylene radical.
- (1S.2S) UR, 2R) is useful as an antihypertensive agent (EP-0 097 584) and, particularly the isomer (1R, 2R), as a cardiac protector (EP-0 429 324) at doses for which the antihypertensive effect does not manifest itself .
- N-methyl (pyridyl-3) -2 tetrahydrothiopyrannecarbothioamide-2-oxide-1- (1R . 2R) can be isolated from a mixture of the forms (1R.2R) and (1S.2S), in particular from the racemic mixture , by chiral phase chromatography (EP-0 097 584) or can be prepared by stereoselective methods (EP-0 426 557). These methods require the use of large quantities of solvents or else the carrying out of a large number of steps.
- N-methyl (3-pyridyl) -2 tetrahydrothiopyrannecarbothioamide-2-oxide-1- (1R.2R) can be obtained at starting from a salt of the mixture of trans isomers (1R, 2R) and (1S.2S) and in particular of the racemic mixture with an optically active acid.
- the method according to the invention consists in selectively precipitating in a suitable solvent a salt of the trans isomer (1R.2R) with an optically active acid and then in liberating the trans isomer (1R.2R) from its salt.
- an optically active acid chosen from (-) - camphanic acid and (+) - 3-bromo-10 camphor-10 sulfonic acid.
- the solvents which are particularly suitable for the selective crystallization of the salt of the trans isomer (1R.2R) with an optically active acid are preferably chosen from water, aliphatic alcohols containing 1 to 4 carbon atoms such as methanol , ethanol or isopropanol, and hydro-alcoholic mixtures.
- (1R.2R) is released from its salt by means of an inorganic or organic base, operating in water or in a mixture consisting of water and an immiscible solvent in which the trans isomer (1R, 2R ) is soluble.
- mineral base hydroxides or carbonates of alkali metals (sodium hydroxide, potassium hydroxide, sodium carbonate) are preferably used.
- organic base tertiary aliphatic amines (triethylamine) or pyridine can be used, the basicity of which is strong enough to release the optically active acid from its salt.
- potash is used in a hydroorganic medium such as a water-halogenated aliphatic hydrocarbon mixture such as a water-methylene chloride mixture: in this way, the isomer trans (1R, 2R) passes into solution in the organic solvent as it is formed, the salt of the optically active acid remaining in aqueous solution.
- a hydroorganic medium such as a water-halogenated aliphatic hydrocarbon mixture such as a water-methylene chloride mixture
- N-methyl (3-pyridyl) -2 tetrahydrothiopyrannecarbothioamide-2-oxide-1- (1R.2R) is separated from its solution according to the usual methods and it can be purified according to known techniques, for example by crystallization.
- the mixture of trans isomers (1R.2R) and (1S.2S) of N-methyl (pyridyl-3) -2 tetrahydrothiopyrannecarbothioamide-2-oxide-1, and more particularly the racemic mixture, can be prepared under the conditions described in European patent EP-0 097 584.
- the following examples illustrate the present invention.
- the enantiomeric excess is close to 100%.
- the yield is 33.4%.
