PROCESS FOR PREPARING 6-AMINO-PENICILLANIC ACID DERIVATIVES

摘要

1. Claims (for the Contracting States : CH, IT, LI, LU, NL, SE) A process for the manufacture of 6-aminopenicillanic acid derivatives of the general formula see diagramm : EP0049891,P5,F1 in which R represents hydrogen or a readily hydrolyzable ester group, as well as of pharmaceutically compatible salts of these compounds, characterized by hydrogenating a compound of the general formula see diagramm : EP0049891,P5,F2 in which R has the significance given above and R**1 signifies a hydrogenolytically cleavable group, or a salt of such a compound in the presence of palladium/carbon, whereafter, if desired, an ester of formula I obtained is subjected to an ester cleavage, if desired a carboxylic acid of formula I obtained is treated with an agent yielding the ester group R and, if desired, a compound of formula I obtained is converted into a pharmaceutically compatible salt thereof. 1.
