Processes to produce 3-cefem compounds |
| abstract |
A process for preparing a 3-halogenomethylcefem compound of the formula (2) or a salt thereof in which X1 is a halogen atom, characterized in that a carboxylic acid protecting group at position 4 of a compound of 7- amino-3-halogenomethylcefem of the formula (1) or a salt thereof in which X1 is a halogen atom, and R1 is a benzyl group having a phenyl ring, an electron donor group as a substituent, or a group Diphenylmethyl, which an electron donor group may have in a phenyl ring, is deprotected with a phenol derivative. |
