    摘要: A new process for preparing pure amorphous rosuvastatin calcium, substantially free of impurities, is disclosed. A process comprising hydrolysing a C1 to C5 alkyl ester of rosuvastatin, preferably methyl rosuvastatin or tert-butyl rosuvastatin, with a base, e.g. sodium hydroxide, in the presence of an aprotic solvent, preferably tetrahydrofuran and N,N-dimethyl acetamide, or in the presence of a mixture of an aprotic solvent and water, to obtain a solution of rosuvastatin salt, which may be converted to another rosuvastatin salt using another cation, e.g. with calcium cation to obtain rosuvastatin calcium. Rosuvastatin amine salts may be obtained as well.In another preferred aspect of the invention rosuvastatin free acid may be converted to various rosuvastatin salts, e.g. to rosuvastain calcium, rosuvastatin sodium or various rosuvastatin amine salts, including rosuvastatin solvates, e.g. rosuvastatin calcium hydrate.Rosuvastatin calcium is useful in the treatment of hyperlipidemia, hypercholesterolemia and atherosclerosis.

    摘要: A pure amorphous form of rosuvastatin calcium substantially free from alkali metal impurities is disclosed. A process of preparing a pure amorphous form of rosuvastatin calcium is disclosed, which comprises hydrolysis of C1-C5 alkyl esters of rosuvastatin, preferably tert-butyl ester of rosuvastatin, with an organic nitrogen base, e.g. guanidines, amidines, amines and quaternary ammonium hydroxides, in the presence of water, optionally containing aprotic solvent, following the conversion of thus obtained rosuvastatin salt with a source of calcium to obtain rosuvastatin calcium, which is then isolated. An alternative process is disclosed, which comprises the conversion of numerous novel ammonium salts of rosuvastatin, preferably tert-octylammonium salt of rosuvastatin, with the source of calcium to desired commercial rosuvastatin calcium. Rosuvastatin calcium is an inhibitor of HMG CoA reductase, useful in the treatment of hyperlipidemia, hypercholesterolemia and atherosclerosis.
