| titleOfInvention | process for cefaclor synthesis and process for obtaining cefaclor |
| abstract | process for the synthesis of cefaclor the present invention relates to a process for the synthesis of cefaclor, a process which comprises reaction of 7-amino-3-chloro cephalosporanic acid (7-acca) with d-phenylglycine in activated form (pga) in the presence of an enzyme in a reaction mixture to form cefaclor, in which at least part of 7-acca and / or pga is added to the reaction mixture during the course of the reaction. the invention also relates to an aqueous mixture comprising an amount of cefaclor of> 10% (weight / weight), an amount of 7-amino-3-cephalosporanic acid of <2% (weight / weight) and an amount of d -phenylglycine <2% (weight / weight) and a process for the recovery of cefaclor from this aqueous mixture. the invention also relates to cefaclor in crystal form having an absorbance at 400 nm (at ~ 400 ~) of less than 0.250. |
