摘要

Procedure for obtaining hydrates from the benzathic salt of acid 3 ((((5-methyl-1,3,4-thiadiazol-2-yl) thio) methyl) -8-oxo-7 ((1H-tetrazol-1- ilacetyl) amino) cephalosporanic, essentially characterized in that it consists of reacting an organic cefazolin salt, dissolved in aqueous organic medium, at a temperature between 0 and 10ºC with continuous agitation, with an aqueous solution of benzathine diazetate at a temperature of 25º c. 35º c, under agitation of cefazolin, which is separated by filtration by drying the cake at a temperature not higher than 40ºC by conventional means.
