Preparing 2-methyl-2-hydroxy-propyl piperazine-carboxylate¹compounds |
| abstract |
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.n[US4550164A] |
