The crystal structure of methyl 9-(4-methoxyphenyl)-8a,9,9a,10,11,12,13,14a-octa hydro-8H-benzo[f]chromeno[3,4-b]indolizine-8a-carboxylate has been determined by means of X-Ray diffraction. The compound crystallizes in the monoclinic space group P21/c with a = 11.288(11) Å, b = 23.760(2) Å, c = 9.202(8) Å and b = 112.292(3)º. The pyrrolidine ring adopts an envelope conformation and the piperidine ring exhibits a chair conformation. The mean plane of the naphthalene ring system makes a dihedral angle of 55.90 (6)º with the methyl benzene ring. The naphthalene ring and tetrahydro pyran ring is almost planar and the dihedral angle between these rings is 9.43 (5)º. The molecular structure of the compound is stabilized by weak intramolecular C–H···N interaction and the crystal packing of the compound is controlled by weak intermolecular C–H···O and C–H···p interactions.
