  Verfahren zur Darstellung von Bromdiäthylazetylharnstoff. Das Stammpatent betrifft ein Verfahren zur Darstellung des   Bromdiäthylazetyl-   harnstoffes der Formel : 
 EMI1.1 
 der wertvolle therapeutische Eigenschaften besitzt. Dieses Verfahren besteht dam, dass man Bromdiäthylazetylhaloide auf Harnstoff einwirken lässt. Es wurde nun gefunden, dass man diesen Körper auch dadurch erhalten kann, dass man an Bromdiäthylazetylcyanamid Wasser anlagert. 



     Beispiel. IUO   Teile Bromdiäthyazetylcyanamid, ein in langen Nadeln kristallisierender 
 EMI1.2 
 mit 300 Teilen 98prozentiger Schwefelsäure gemischt. Nach 48 Stunden giesst man in Eis-   wahser und extrahiert   den Bromdiäthylazetylharnstoff mit Äther. Nach dem Umkristallisieren aus Alkohol schmilzt das Produkt bei 114 bis 118  C. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  Process for the preparation of bromine diethyl acetylurea. The parent patent relates to a process for the preparation of bromodiethylazetyl urea of the formula:
 EMI1.1
 which has valuable therapeutic properties. This procedure consists of allowing dietary bromine acetyl halides to act on urea. It has now been found that this body can also be obtained by adding water to Bromdiäthylazetylcyanamid.



     Example. IUO parts Bromdiäthyazetylcyanamid, a crystallizing in long needles
 EMI1.2
 mixed with 300 parts of 98 percent sulfuric acid. After 48 hours, it is poured into ice water and the bromine diethyl acetylurea is extracted with ether. After recrystallization from alcohol, the product melts at 114 to 118 C.

PATHNT-ANSPRt'c'H : Abänderung des durch das Stammpatent geschützten Verfahrens zur Darstellung von Bromdiäthylazetylharnstoff, darin bestehend, dass man, anstatt Bromdiäthylazetylhaloide auf Harnstoff einwirken zu lassen, hier an Bromdiäthyiazetytcyanamid Wasser anlagert. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATHNT REQUEST: Modification of the process for the preparation of bromodiethylazetylurea, which is protected by the parent patent, consists in the fact that instead of allowing bromodiethylazetyl haloids to act on urea, water is attached to bromodiethylacetcyanamide here. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
