Methyl [6-Amino-5-Cyano-4-(4-Methoxyphenyl)-Pyrano[2,3-c]Pyrazol-3-yl]Acetate

Abstract

In the title compound, C<inf>17</inf>H<inf>16</inf>N<inf>4</inf>O <inf>4</inf>, the dihedral angle between the planar nine-membered bicyclic ring system and the benzene ring is 81.9 (1)°. Intramolecular N-H⋯O and intermolecular N-H⋯O, N-H⋯N and C-H⋯N hydrogen bonds are effective in stabilizing the molecular and crystal structure. © 2005 International Union of Crystallography Printed in Great Britain - all rights reserved.
