Abstract

Improvements in the object of the patent of invention no. 302,954 which relates to the process of manufacturing new tetracycline compounds characterized in that the reaction of the sulfonic group of the balsamic derivative with the dimethylsmino group of the tetracycline, is carried out by reacting a salt alkali of the phenolsulfonic acid with the tetracycline hydrochloride or its derivatives, under such conditions, that the acid radical of the tetracycline salt reacts with the alkaline base of the phenolsulfonic salt with formation of the corresponding alkali chloride, this reaction being carried out in a liquid medium in which the phenolsulfonic compound of the tetracycline is soluble but neither the alkaline salt of the phenolsulfonic acid nor the resulting alkali metal chloride is soluble in order to separate it afterwards by precipitation and then the resulting solution is treated with another solvent in which the liquid medium previously used but it is not the phenolsulfonic compound of tetracycline, which is separated by precipitation and further centrifugation, and then said compound is dried.
