Abstract
The present invention relates to the novel compound N-[3-(1'-3"-Oxapentamethyleneamino-ethylideneamino)-2,4,6-triiodobenzoyl]- .beta.-amino-.alpha.methylpropionitrile which due to the sparing solubility in water, can be purified readily in a simple manner and can be used for the preparation of the known active compound for agents for peroral rapid cholecystography N-[3-(1'-3"-oxapentamethyleneamino-ethylideneamino)-2,4,6-triiodobenzoyl]- .beta.-amino-.alpha.-methyl propionic acid.
Claims3
A process for production of N-[3-(1'-3"-oxapentamethyleneamino-ethylideneamino)-2,4,6-triiodobenzoyl]- .beta.-amino-.alpha.-methylpropionic acid comprising using N-[3-(1'-3"-Oxapentamethyleneamino-ethylideneamino)-2,4,6-triiodobenzoyl]- .beta.-amino-.alpha.-methylpropionitrile as starting material and hydrolyzing said nitrile compound by heating with a strong acid or an alkaline hydrolyzing agent in aqueous medium.
