Description
<B>Verfahren zur Herstellung von</B> 2-(3',5'-Dijod-salicoylamino)-pyrimidin. Das vorliegende Patent betrifft ein Ver fahren zur Herstellung von 2-(3',5'-Dijod- salicoylamino)-pyrimidin, welches dadurch gekennzeichnet ist, dass man 3,5-Dijod-sali- eylsäurechlorid auf 2-Amino-pyrimidin ein wirken lässt.
Die neue Verbindung entspricht der Formel
EMI0001.0009
und besitzt fungizide Eigenschaften. <I>Beispiel:</I> 20,4 g 2-Amino-pyrimidin werden in 200 g trockenem Benzol suspendiert. Unter gutem Umschütteln gibt man 44 g 3,5-Dijod- salicylsäureehlorid, welches in 150 g Benzol gelöst ist, portionenweise zu. Gleichzeitig wird die Temperatur allmählich gegen 60' gesteigert, unter Zugabe von 30 g Pyridin in drei Portionen.
Die letzte Portion des Säure- chlorides bzw. Pyridins erfolgt nach 30 Mi nuten, gerechnet vom Beginn der Reaktion an. Durch Kochen am Rüekfluss während vier Stunden wird die Reaktion beendigt und das Aktionsprodukt erkalten gelassen. Man nutscht das Reaktionsprodukt ab, wäscht mit Wasser und kristallisiert aus Eisessig um.
Durch wiederholtes Umkristallisieren aus lfetha.nol wird die Substanz gereinigt. Sie besitzt die Formel

<B> Process for the preparation of </B> 2- (3 ', 5'-diiodo-salicoylamino) -pyrimidine. The present patent relates to a process for the production of 2- (3 ', 5'-diiodosalicoylamino) pyrimidine, which is characterized in that 3,5-diiodosalicylic acid chloride is acted on 2-aminopyrimidine leaves.
The new compound corresponds to the formula
EMI0001.0009
and has fungicidal properties. <I> Example: </I> 20.4 g of 2-aminopyrimidine are suspended in 200 g of dry benzene. 44 g of 3,5-diiodosalicylic acid chloride, which is dissolved in 150 g of benzene, are added in portions with thorough shaking. At the same time, the temperature is gradually increased to 60 ', with the addition of 30 g of pyridine in three portions.
The last portion of the acid chloride or pyridine takes place after 30 minutes, calculated from the start of the reaction. The reaction is ended by boiling on the reflux for four hours and the action product is allowed to cool. The reaction product is filtered off with suction, washed with water and recrystallized from glacial acetic acid.
The substance is purified by repeated recrystallization from lfetha.nol. She owns the formula
