Abstract:A synthetic process was developed for the preparation of cephalosporin cefdinir using S-thio-benzothiazole-(Z)-2-(2-aminothiazole-4-yl-)-acetoxy imine acetate(cefdinir side chain active ester)and(6R,7R)-7-amino-8-oxo-3-vinyl-5-thia-1-azabicyclo[4.2.0] oct-2-ene-2-carboxylic acid(7-AVNA)as the starting materials through a series reactions. In these reactions sodium hydroxide was used as condensing agent; ammonium carbonate and potassium carbonate were used as the buffer catalyst for the removal of acetyl group by hydrolysis. Yield was 85.2%.
