Sažetak

The synthesis of diethyl-4,5,6 , 7-tetrahydroindazol-3-one-5,5-
dicarboxylate (I) and its reductive cleavage into 2-carboxamide-
4,4-dicarbethoxy-cyclohexylamine (II) using Raney nickel-catalyst
in iso-propanol and methanol were described.
The reductive opening of I in ethanol favored the formation
of Schiff base, 2-carboxamide - 4,4 - dicarbethoxy - N - ethylidenecyclohexylamine
(III).
