title: Ethyl 3-amino-1-phenyl-1H-benzo[f]chromene-2-carboxyl-ate.
abstract: The pyranyl ring of the title compound, C(22)H(19)NO(3), adopts a flattened-boat conformation. The dihedral angle between naphthalene and phenyl rings is 78.3 (1)°The mol-ecule also features an intra-molecular N-H⋯O(carbon-yl) hydrogen bond. Adjacent mol-ecules are linked by an inter-molecular N-H⋯O(carbon-yl) hydrogen bond, forming a zigzag chain that runs along the c axis.
