Abstract
The invention relates to a new process for the preparation of compounds of general formula (I), (wherein R stands for piperazinyl, 4-methyl-piperazinyl or 4-ethyl-piperazinyl group) and pharmaceutically acceptable salts thereof which comprises reacting a compound of general formula (II), (wherein R<1> and R<2> stand for halogen, for an aliphatic acyloxy group containing 2 to 6 carbon atoms and optionally substituted by halogen, or for an aromatic acyloxy group containing 7 to 11 carbon atoms) with a piperazine derivative of general formula (III), (wherein R<3> stands for hydrogen, methyl or ethyl) or a salt thereof and subjecting the compound of general formula (IV) thus obtained, (wherein R, R<1> and R<2> are as stated above) to hydrolysis after or without isolation and if desired converting the compound of general formula (I); thus obtained into a salt thereof or setting free the same from its salt. The compounds of general formula (I) are known antibacterial agents. The advantage of the present invention is that it makes the desired compounds of general formula (I) available in a simple manner, with high yields and in a short reaction time.
