    摘要: A process for the preparation of amorphous atorvastatin calcium. The process includes providing a reaction mixture having a pH between 6.5 and 8.0 containing a sodium salt of atorvastatin and tetrahydrofuran. A non-cyclic chlorinated organic solvent selected from the group consisting of dichloromethane, trichloroethane, tetrachloroethane and chloroform or addition of cyclic hydrocarbon solvent selected from the group consisting of cyclohexane, cyclopentane and methyl cyclohexane is added to provide a mixture of organic solvents. An equivalent or an excess quantity of a source of calcium ions selected from the group consisting of calcium acetate and calcium chloride is added. Amorphous atorvastatin calcium is isolated from an organic phase comprising the mixture of organic solvents.

    摘要: A novel process for the preparation of calvulanic acid and pharmaceutically acceptable salt thereof, such as potassium clavulanate, is described. According to the novel process, crude clavulanic acid, which is present in the form of an extract in an organic solvent, such as ethyl acetate, the extract having been obtained in known manner upon fermentation with a calvulanic acid producing microorganism, is reacted with substituted alkylenediamines of the formula II ##STR1## wherein the substituents R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 and n have the meanings as defined in claim 1, e.g. with N,N'-diisopropylethylenediamine, to the novel alkylenediammonium diclavulanates of the formula I ##STR2## wherein the substituents R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 and n have the meanings as defined in claim 1, e.g. to N,N'-diisopropylethylenediammonium diclavulanate. The obtained compounds of the formula I are optionally isolated and converted with alkali alkanoates, such as potassium 2-ethylhexanoate in isopropanol, to potassium clavulanate.Because of their high inhibitory action against beta-lactamases and because of a significant synergistic action in combination with the beta-lactam antibiotics from the group of penicillins and cephalosporins, clavulanic acid and pharmaceutically acceptable salts thereof are valuable compounds for the preparation of galenic compositions, which are active in the treatment of infectious diseases induced by numerous grampositive and gram-negative microorganisms.
