Process for preparing 2-piperazine carboxylic acid derivatives |
| abstract |
The invention concerns a process fro preparing 2-piperazine carboxylic acid amides of general formula (I), wherein a piperazine carboxylic acid, N-acylated with a halogenating agent to form a piperazine carboxylic acid anhydride of general formula (IV), is cycled and finally converted into the end product with an amino component. The 2-piperazine carboxylic acid amides of general formula (I) are inter alia valuable intermediate products for preparing orally active HIV-1 protease inhibitors. |
