7synthesis methods
The synthesis of 7-Aminocephalosporanic acid involves esterification of semi-synthetic cephalosporin-cephalosporin C with trimethylchlorosilane, followed by phosphorus pentachloride chloride and butanol etherifying. The final product is obtained through hydrolysis. The yield from cephalosporin C sodium to 7-ACA is approximately 50%.
