Ethyl 4-(3-Hydroxy-6-Methyl-4-Oxo-4H-Pyran-2-ylmethyl)Piperazine-1-Carboxylate

Abstract

The title compound, C<inf>14</inf>H<inf>20</inf>N<inf>2</inf>O<inf>5</inf>, was synthesized as a Mannich base and characterized by IR, 1H NMR, GC mass spectra and elemental analysis. The piperazine ring displays a chair conformation, and the crystal structure is stabilized by O-H⋯O and C-H⋯O intra- and intermolecular hydrogen bonds. © 2004 International Union of Crystallography Printed in Great Britain - all rights reserved.
