Source of material

4-Pyridinecarboxaldehyde, ethl acetoacetate and ammonium acetate was added to ethanol under stirring at room temperature and the reaction mixture was refluxed for 8 h. Concentration in vacuum followed by recrystallization from ethanol afforded a white solid.

Experimental details

The Amide hydrogen atom as well as those at water were refined freely. Fixed Uiso at 1.2 times of all C(H) groups, and 1.5 times of all C(H,H,H) groups. The hydrogen atoms attached to carbon were placed on calculated positions with the help of the SHELX program (AFIX 43 or 137 option) [2].

Discussion

To our knowledge the title compound, is known [3, 4] , but was not characterized by X-ray single crystal structure analysis. X-ray crystallography analyses reveal that the title compound is a monohydrate. Characteristic torsion angel are: C3—C4—C13—C14: 36.9°, C2—C1—C5—C6: 27.5°, C2—C3—C11—O1: 32.8°, C10—C2—C3—C11: 6.3°. This indicates a highly rotational freedom of the pyridyl group linked at C1 and C4 (cf. the figure). All the lengths and angles are in the normal range [5].
