摘要: The aim of the invention to provide a less complex method for the production of A-ring aromatized acetyl minocyclines of the formula (I), wherein R1 to R5=acetyl and/or H, which can also be used on an industrial scale, is achieved in that minocycline hydrochloride is reacted with acetanhydride in the presence of a proton catcher, the reaction product is subjected to chromatographic filtration using a carrier material and an eluant, the eluant is distilled off, and the product is subsequently cleaned by recrystallization.
