| titleOfInvention | A PROCEDURE FOR THE PREPARATION OF CRYSTALLINE CEFTAZIDYME BIS-HYDROBROMIDE MONOHYDRATE |
| abstract | PROCEDURE FOR THE PREPARATION OF CEFTAZIDIMA CRYSTALLINE BIS-HYDROBROMIDE MONOHYDRATE. IT INCLUDES: A) REACTING (A) WITH 98% FORMIC ACID AND 48% HYDROBROMIC ACID, TO SEPARATE THE CARBOXY PROTECTIVE T-BUTYL GROUP AND THE AMINO PROTECTIVE TRITILO GROUP AND FORM A BIS-HYDROBROMIDE SALT OF ( TO); B) FILTER TO THE MIXTURE OF A), TO ISOLATE THE CRYSTALLINE SALT AND SEPARATE THE INSOLUBLE TRIPHENYLCARBINOL; C) DILUTE BY FILTERING WITH ACETONE, METHYL ETILCETONE OR CYCLOHEXANE; D) COOL TO THE DILUTION BETWEEN 10 AND 20JC TO CRYSTALLIZE THE A-BIS-HYDROBROMIDE A-MONOHYDRATE OF (A); E) FILTER TO THE DILUTION WITH THE CRYSTAL SALT AND STEM WATERS, TO SEPARATE THE STOCK WATERS; F) WASH IN CRYSTALLINE SALT WITH WATER AND G) DRY UNDER VACUUM AND AT ROOM TEMPERATURE IN CRYSTALLINE SALT. BEING (A) CEFTAZIDIMA O (6R, 7R) -7 - ((Z) -2- (2-TRITILAMINO-1,3-THIAZOL-4-IL) -2-T-BTILOXICARBONILPROP-2-OXIMINO) ACETAMIDO) - 3- (1-PYRIDINIOMETIL) -3-CEFEM-4-CARBOXYLATE. |
