Ethyl 3-amino-1-phenyl-1H-benzo[f]chromene-2-carboxylate

Abstract

The pyranyl ring of the title compound, C22H19NO3, adopts a flattened-boat conformation. The dihedral angle between naphthalene and phenyl rings is 78.3 (1)°The molecule also features an intramolecular N—H...Ocarbonyl hydrogen bond. Adjacent molecules are linked by an intermolecular N—H...Ocarbonyl hydrogen bond, forming a zigzag chain that runs along the c axis.
