摘要:
This invention relates to a process for preparing basic organic nitrogen-containing compounds by (a) reduction with lithium aluminum hydride, (b) hydrolysis of the resultant mixture by addition to an aqueous solution in which substances containing null-hydroxycarboxyl and/or null-aminocarboxyl groups are dissolved, and (c) separation of the two resultant phases at a pH of the aqueous phase of from 7 to 12.
摘要:
Heterocyclic derivatives of the formula (I) 1 wherein each symbol is as defined in the specification, pharmaceutically acceptable salts thereof and method of producing them. Pharmaceutical compositions containing the heterocyclic derivative or a pharmaceutically acceptable salt thereof, particularly, ACAT inhibitors and lipoperoxidation inhibitors. The heterocyclic derivatives and pharmaceutically acceptable salts thereof of the present invention show superior ACAT inhibitory activity and lipoperoxidation inhibitory activity, and are useful as ACAT inhibitors and hyperlipemia inhibitors. To be specific, they are useful for the prevention and treatment of arteriosclerotic lesions of arteriosclerosis, hyperlipemia and diabetes, as well as ischemic diseases of brain, heart and the like.
