PROCESS FOR PREPARING 2-METHYL-2-HYDROXYPROPYL PIPERAZINE- 1-CARBOXYLATE COMPOUNDS |
摘要 |
Isobutylene carbonate and certain 1-substituted piperazine compounds are reacted in a process that forms 2-methyl-2-hydroxypropyl 4-substituted piperazine-1-carboxylate compounds which are medicinal agents or synthetic intermediates for such agents. The features of the process allow the preparation of an essentially pure 2-methyl-2-hydroxypropyl carboxylate compound. |
