Abstract
Improvements in the patent of invention no. 376,271 by "procedure for the preparation of semisynthesis penicillins", according to which the intermediate resulting from the combination of a dimethylformamide N-halidehalosulfite and a carboxylic acid is reacted with a tertiary amine salt 6-apa in the presence of fatty acids, characterized in that to the transformation product, water and a aldehyde or a low molecular weight ketone are added, adjusting the ph from 2 to 2.5, obtaining by decantation an organic phase, which is again adjusted to ph 6-6.5 with 2-ethylhexanoate sodium and then by dilution in an aliphatic hydrocarbon, precipitating the corresponding penicillin.
