Abstract
Improvements in the object of main patent no. 392,136 by a process for obtaining a doxycycline salt, characterized in that 11a-chloro-6-deoxy-6-demethyl-6-methylene-5-hydroxytetracycline is reacted in a suitable medium in form of metaphosphoric acid complexes, of empirical formula (C22H22ClN2O8) z. (HPO3) n, where n = 1 to 6, z = 1 to 6 and z <= n, with L-2-acetamido-3-mercapto acid -propionic, treating the reaction mixture with hydrazine in the presence of a noble metal on carbon support as catalyst.
