    摘要: The present invention relates to a process for the preparation of compounds of the general Formula I ##STR1## and pharmaceutically acceptable salts thereof (wherein R stands for piperazinyl or 4-methyl-piperazinyl) which comprises reacting a compound of the general Formula II ##STR2## (wherein R.sup.1 and R.sup.2 stand for halogen; an aliphatic acyloxy group comprising 2-6 carbon atoms and optionally substituted by halogen; or an aromatic acyloxy group comprising 7-11 carbon atoms) with a piperazine of the general Formula III ##STR3## (wherein R.sup.3 represent hydrogen or methyl) or a salt thereof, hydrolysing the compound of the general Formula IV ##STR4## thus obtained (wherein R, R.sup.1 and R.sup.2 are as stated above) without or after hydrolysis and if desired converting the compound of the general Formula I thus obtained into a salt thereof or setting free the same from its salt.The compounds of the general Formula I are known antibacterial agents.The advantage of the process of the present invention is that it enables the preparation of the compounds of the general Formula I in a simple manner, with high yields and in a short reaction time.
