Process for preparation of 7-amino-cephalosporanic acid compound |
| abstract |
In the process for manufacturing 7-amino-cephalosporanic acid by converting a cephalosporin C silyl ester into a 7-imide-halide, converting the latter into the corresponding imino-ether and splitting the double bond of the latter, the step which comprises reacting the imide halide with the imino-ether at a temperature between -15* and + 30*C. |
