Cefazedone Sodium,Arocor Holdings Inc.

Manufacturing Process

A solution of 1 eq. of the tert-butyl ester of 7-aminocephalosporanic acid and 1 eq. of dicyclohexylcarbodiimide in 100 ml of methylene chloride/DMF (1:1) is cooled to 0°C. The mixture is combined with 1 eq. of 3,5-dichloro-4- pyridone-1-acetic acid; after 5 min the ice bath is removed and the mixture agitated for another 30 min at 25°C. The thus-formed urea is filtered off and the filtrate filtered over silica gel (eluent: ethyl acetate/1% methanol). The solvent is concentrated by evaporation, and the thus-obtained tert-butyl ester of 7-(3,5-dichloro-1,4-dihydro-4-oxo-1-pyridylacetamido)cephalosporanic acid is crystallized from ether.
1 eq. of the tert-butyl ester is dissolved in 30 ml of trifluoroacetic acid. After 30 minutes, the solution is evaporated and the thus-produced 7-(3,5-dichloro- 1,4-dihydro-4-oxo-1-pyridylacetamido)cephalosporanic acid crystallized from ether.
1 eq. of the obtained 7-(3,5-dichloro-1,4-dihydro-4-oxo-1-pyridylacetamido) cephalosporanic acid is dissolved in 60 ml of saturated aqueous sodium bicarbonate solution at a pH of below 7 and combined with 1 eq. of 5-methyl- 1,3,4-thiadiazole-2-thiol in 20 ml of acetone. The reaction solution is agitated for 2 hours at 80°C and at a pH of 6.3 under a nitrogen atmosphere. The acetone is thereupon removed, the solution is washed with ether and acidified to pH 2. The thus-obtained 3-(1-methyltetrazolyl-5-mercaptomethyl)-7-(3,5- dichloro-1,4-dihydro-4-oxo-1-pyridylacetamido)-3-cephem-4-carboxylic acid is filtered off and dried. IR spectrum confirmed the structure of cefazedone.
In practice it is usually used as sodium salt.
