N′-[1-(4-Aminophenyl)ethyl]pyrazine-2-carbohydrazide
The title compound, C(13)H(13)N(5)O, crystallizes with two mol-ecules in the asymmetric unit. The crystal structure is stabilized by intra-molecular N-H⋯N and N-H⋯O hydrogen bonds. The dihedral angles between the pyrazine ring and the 4-aminolphenyl ring are 2.5 (1) and 6.5 (1)° in the two molecules.

* The trichloroacetic acid extracts were first acidified with sulfuric acid3 and kept overnight at 38” for decarboxylation of acetoacetate. The fluid was then neutralized with sodium hydroxide and phosphate, and the acetone distilled by the procedure of Folin.4 Acetone was determined calorimetrically by the method of Behre.6 Analogous results were obtained with the determination procedure of Le...

متن کاملN′-[(E)-Benzylidene]-1-ethyl-7-methyl-4-oxo-1,4-dihydro-1,8-naphthyridine-3-carbohydrazide
In the title compound, C(19)H(18)N(4)O(2), the 1,8-naphthyridine ring system is essentially planar [r.m.s. deviation = 0.011 (3) Å]. The dihedral angle between the naphthyridine ring system and the phenyl ring is 28.95 (7)°. The carbohydrazide H atom is involved in an intra-molecular N-H⋯O hydrogen bond, forming a six-membered hydrogen-bonded ring. In the crystal, the mol-ecules arrange themsel...
