Process for preparing basic organic nitrogen-containing compounds by reduction with lithium aluminum hydride |
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 alpha-hydroxycarboxyl and/or alpha-aminocarboxyl groups are dissolved, and (c) separation of the two resultant phases at a pH of the aqueous phase of from 7 to 12.
