| 摘要 |
The present invention relates to the novel compound N-[3-(1'-3''-Oxapentamethyleneamino-ethylideneamino)-2,4,6-triiodobenz oyl]- 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-triiodobenz oyl]- beta -amino- alpha -methyl propionic acid. |
