| titleOfInvention | METHOD OF PRODUCING 7{62 -ACYLAMIDO-3-METHYLCEPH-3-Em-4-CARBOXYLIC ACID ESTERS[US3725399A] |
| abstract | The invention relates to a process for the preparation of 7 beta -acylamido-3-methylceph-3-em-4-carboxylic acid esters from 6 beta -acylamido penicillanic acid 1-oxide esters in the presence of catalysts which are salts or complexes of acids with nitrogen bases having a pKb of not less than 4. The salts or complexes may be formed in situ.n[US3725399A] |
