Verfahren zur Herstellung des neuen 2-[1- (5-Nitrofurfuryliden-amino) - - 2, 4-dioxo-imidazolidyl- (3) j-äthylcarbaminsäure-äthylesters
Die Erfindung betrifft ein Verfahren zur Herstellung des neuen 2-[l- (fi-Nitrofurfuryliden-amino) - - 2, 4-dloxo-imidazolidyl- (3)]-äthylcarbaminsäure-äthylesters der Formel :
EMI1.1
EMI1.2
<Desc/Clms Page number 2>
Reaktionsprodukt wird abfiltriert, mit Wasser, Alkohol sowie Äther gewaschen und bei 1100C getrocknet..
Auf diese Weise erhält man 59 g (= 67tu0 d. Th.) des rohen 2-[1- (5-Nitrofurfuryliden-amino) -2, 4-dioxo- -imidazolidyl-(3)]-äthylcarbaminsäure-äthylesters. Nach zwei Umkristallisationen aus 100 cm3 Nitromethan unter Zugabe von Tierkohle schmilzt die Verbindung (46 g) bei 176-177 C.

Process for the preparation of the new 2- [1- (5-nitrofurfurylidene-amino) - - 2, 4-dioxo-imidazolidyl- (3) j-ethylcarbamic acid ethyl ester
The invention relates to a process for the preparation of the new 2- [l- (fi-nitrofurfurylidene-amino) - - 2, 4-dloxo-imidazolidyl- (3)] - ethylcarbamic acid ethyl ester of the formula:
EMI1.1
EMI1.2
<Desc / Clms Page number 2>
The reaction product is filtered off, washed with water, alcohol and ether and dried at 1100C ..
In this way, 59 g (= 67tu0 of theory) of the crude ethyl 2- [1- (5-nitrofurfurylidene-amino) -2, 4-dioxo- imidazolidyl- (3)] ethylcarbamic acid are obtained. After two recrystallizations from 100 cm3 nitromethane with the addition of animal charcoal, the compound (46 g) melts at 176-177 C.
