Description
Terfahren zur Herstellung der γ-(4-Oxy-3,5-dijod-phenyl)-¯-phenyl-buttersÏure.
Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung der y- (4-Oxy- 3, 5-dijod-phenyl)-¯-phenyl-buttersÏure, das dadurch gekennzeichnet ist, dass man y- (4- Oxy-phenyl)-¯-phenyl-buttersÏure mit einem jodierenden Mittel behandelt.
Die neue Verbindung soll insbesondere als Gallenkontrastmittel Verwendung finden.
Beispiel :
25, 6 g γ-(4-Oxy-phenyl)-¯-phenyl-butter- sÏure vom F = 135 (hergestellt durch Kon- densation von Hydrozimtsäure mit 4-Oxybenzaldehyd in Gegenwart von Essigsäure- anhydrid und Hydrierung der erhaltenen Benzylidenverbindung vom Smp. = 189¯ vermittels Natriumamalgam) werden in 800 cm3 n/2 Natronlauge gel¯st und unter Rühren langsam bei gew¯hnlicher Temperatur mit einer Losung von 50, 8 g Jod und 50, 8 g Jod- kalium in 250 cxn3 Wasser versetzt.
Aus der annÏhernd neutralen, schwach gefÏrbten L¯ sung wird das Jodierungsprodukt durch Zusatz von schwefliger SÏure und SalzsÏure aus ! gefällt. Es wird noch eine 7eitlang ger hrt, das fast farblose Produkt dann abgesaugt und mit Wasser ausgewaschen. Das Rohprodukt wird zur Reinigung aus einem Chloroform-PetrolÏthergemisch umkristallisiert, Smp. 140-141¯.
PATENTANSPRUC
Verfahren zur Herstellung der y- (4-0xy- 3, 5 - dijod - phenyl)-¯-phenyl-buttersÏure, dadurch gekennzeichnet, da¯ man y- (4-Oxy- phenyl)-¯-phenyl-buttersÏure mit einem jo dierenden Mittel beha-ndelt.
Die neue Verlindung schmilzt bei 140 bis 141 .
**WARNUNG** Ende DESC Feld konnte Anfang CLMS uberlappen**.
Method for the preparation of γ- (4-oxy-3,5-diiodo-phenyl) -¯-phenyl-butyric acid.
The present patent is a process for the preparation of y- (4-oxy-3, 5-diiodophenyl) -¯-phenyl-butters -ure, which is characterized in that y- (4-oxy-phenyl) -¯ -phenyl-butyric acid treated with an iodine agent.
The new compound is intended to be used in particular as a biliary contrast medium.
Example:
25.6 g of γ- (4-oxy-phenyl) -¯-phenyl-butyric acid of F = 135 (produced by condensation of hydrocinnamic acid with 4-oxybenzaldehyde in the presence of acetic anhydride and hydrogenation of the benzylidene compound obtained from Melting point = 189¯ by means of sodium amalgam) are dissolved in 800 cm3 n / 2 sodium hydroxide solution and slowly mixed with a solution of 50.8 g iodine and 50.8 g iodo- potassium in 250 cxn3 water while stirring at normal temperature .
The iodination product is made from the almost neutral, slightly colored solution by adding sulfurous acid and hydrochloric acid! like. The mixture is stirred for a while, the almost colorless product is then suctioned off and washed out with water. For purification, the crude product is recrystallized from a chloroform-petroleum ether mixture, mp 140-141¯.
PATENT CLAIM
Process for the preparation of y- (4-oxy- 3, 5-diiodo-phenyl) -¯-phenyl-butyric acid, characterized in that y- (4-oxy-phenyl) -¯-phenyl-butyric acid with a jo ding means huddled.
The new compound melts at 140 to 141.
** WARNING ** End of DESC field could overlap beginning of CLMS **.
