Versuchsvorschrift

Into an apparatus similar to that in Example 1, were charged 103.1 g (1 mole) of diethylenetriamine and 284.5 g (1 mole) of isostearic acid. At 200° to 210° C., 18 g of water was distilled off to effect the monoamide formation. Then, after the addition of 130.1 g (1 mole) of ethyl acetoacetate, 18 g of water and 46 g of ethanol were distilled off at 150° to 160° C. to obtain 4-isostearamidoethyl-7-methyl-3,6-dihydro-2H-1,4-diazepin-5-one.

Aufarbeitung
