| titleOfInvention | PROCESS TO PREPARE A DERIVATIVE OF PIPERAZINE. |
| abstract | PROCESS FOR THE PREPARATION OF A PIPERAZINE DERIVATIVE, REPRESENTED BY THE GENERAL FORMULA (I), IN WHICH R1 IS A HYDROGEN ATOM OR A LOWER ALKYL GROUP; R2 IS A HYDROXYL GROUP OR AN ARALKYLOXIDE GROUP; R3 IS A HYDROGEN ATOM; AND R4 IS A HYDROGEN ATOM OR LOWER ALCOXYL GROUP, AND ITS PHARMACEUTICALLY ACCEPTABLE SALTS. IT INCLUDES THE FOLLOWING OPERATIONS: FIRST, A COMPOUND OF GENERAL FORMULA (II) IS ADDED TO A SOLVENT; SECOND, THE COMPOUND OF GENERAL FORMULA (II) IS REDUCED, AT A TEMPERATURE INCLUDED BETWEEN ZERO AND THE BOILING POINT OF THE SOLVENT, BY MEANS OF AN ACTION OF REDUCING AGENT; AND FINALLY, IT BECOMES A DERIVATIVE OF PIPERAZINE SO OBTAINED, IN THE CORRESPONDING SALT. OF APPLICATION IN THE PREPARATION OF A DRUG CAPABLE OF IMPROVING BRAIN CIRCULATION. |
