Definitions
- This invention relates to new pharmaceutical intermediates and a process for the preparation thereof.
- the invention relates more particularly to salts of (4R- -cis)-(1 , 1 -dimethyl-ethyl)-6-(2-aminoethyl)-2,2-dimethyl-1 ,3- -dioxane-4-acetate formed with organic acids.
- the aminoethyl derivative of the Formula I is prepared by fractionated distillation carried out at 125-135°C/0.05 Hgmm.
- the purity of the product is not higher than 96 %.
- the disadvantage of this process is that fractionated distillation in high vacuo is a complicated purification method which is only circumstantially feasible on industrial scale.
- reaction scheme B The process set forth in US patent No. 5,103,024 and the corresponding Hungarian patent No. 213,731 is shown on reaction scheme B.
- the compound of the Formula I is purified by column chromatography.
- the drawback of this process is that column chromatography requires large investments and is but difficultly feasible, particularly on industrial scale.
- the purity of the product obtained does not exceed 98.2 %.
- the present invention is based on the recognition that the compound of the Formula I forms stable salts with organic acids. This recognition is so much the more surprising as it is known from prior art that ketales are instable in the presence of acids.
- the two hydroxy groups of the amine derivative of the Formula I are protected by a ketale ring. It was unforeseen that said ketale group would be resistant to organic acids under the reaction conditions used.
- the salts of the present invention are not only stable at room temperature but remain stable even during recrystallization from an organic solvent carried out at higher temperature.
- the following acids may be used for salt formation: an aliphatic monocarboxylic acid, dicarboxylic acid or polycarboxylic acid, cycloalkane carboxylic acid, aliphatic unsaturated carboxylic acid, aromatic carboxylic acid, heterocyclic carboxylic acid or sulphonic acid.
- the following acids are used: acetic acid, butyric acid, valeric acid, isovaleric acid, pivalic acid, oxalic acid, malic acid, succinic acid, malonic acid, citric acid, cyclopropane carboxylic acid, cyclobutane carboxylic acid, cyclopentane carboxylic acid, cyclohexane carboxylic acid, fumaric acid, maleic acid, benzoic acid, m-methyl-benzoic acid, 4-methoxy-benzoic acid, 4-bromo- -benzoic acid, 4-tert.
- butyl-benzoic acid benzenesulfonic acid, methanesulfonic acid, p-methyl-benzenesulfonic acid, p-bromo- -benzenesulfonic acid, nicotic acid, tetrahydrofurane-2- -carboxylic acid or tiophen-3-carboxylic acid.
- pivalic acid is used.
- the reaction may be carried out in an apolar, dipolar aprotic or protic solvent.
- an aliphatic hydrocarbon, aromatic hydrocarbon, halogenated hydrocarbon, ester, nitrile, alcohol or ether may be used. It is preferred to use one of the following solvents: hexane, heptane, petrolether, toluene, benzene, xylene, dichloro methane, chloroform, ethyl acetate, acetonitrile, methanol, ethanol, isopropanol, tetrahydrofurane, dioxane or diethyl ether.
- a solvent mixture may also be used as reaction medium. It is preferred to use a mixture of heptane and toluene; hexane and toluene; hexane, toluene and tetrahydrofurane; heptane, toluene and tetrahydrofurane; or hexane and diethyl ether.
- the compound of the Formula I and the organic acid are reacted in the form of solutions formed with the same solvent.
- the compound of the Formula I and the organic acid in a molar ratio of 0.5-5, preferably 0.5-2, particularly preferably 0.5-1.2.
- the compound of the Formula I and the organic acid are admixed preferably at room temperature and the reaction may be performed under heating or at room temperature. One may preferably work at the boiling point of the reaction mixture.
- the reaction mixture may be worked up by simple methods. One may proceed preferably by cooling the reaction mixture, isolating the precipitated salt of the compound of the Formula I by filtration or centrifugation, washing the salt with an organic solvent and drying.
- the salt may be purified by recrystallization.
- a crude compound of the Formula I is used as starting material. In this case the expensive and complicated purification of the compound of the Formula I is eliminated.
- the compound of the Formula I is purified by simple recrystallization which can be carried out significantly easier than fractionated distillation performed in high vacuo and column chromatography used in the known methods.
- the present invention provides a product of higher purity than the prior art methods. After a single recrystallization step the purity of the product is > 99 % (according to gas chromatography), after two-fold recrystallization the purity amounts to > 99.95 %. The purity of the product obtained by known methods is lower than 98 %.
- the process of the present invention can be easily carried out on industrial scale too.
- the scaling-up causes no problems.
- the fractionated distillation performed in high vacuo and column chromatography requires considerable investments and is but difficultly feasible on industrial scale.
- the compound of the Formula I is stable and can be stored for a long period of time without decomposition in the form of salts formed with organic acids.
- atorvastatin meeting the requirements of Pharmacopoeia can be prepared.
- Example 1 Further details of the present invention are to be found in the following Examples without limiting the scope of protection to said Examples.
