Abstract
Process for obtaining semisynthesis penicillins, characterized in that the intermediate resulting from the combination of a dimethylformamide N-halide-halosulfite and a carboxylic acid is reacted with a tertiary amine salt of 6-apa in the presence of acids fatty acids, whose pka is less than the pka of 6-apa, to form a penicillin that is isolated, by diluting the reaction mixture in an aliphatic hydrocarbon.
