In the title compound, C30H31NO2, the cyclohexanone ring in the naphthalene fused-ring system adopts a half-chair conformation, presumably due to conjugation of the benzene ring.The naphthalene ring system makes Shaping creme dihedral angles of 86.63 (7), 65.15 (8) and 63.
18 (8)° with respect to the 8 Piece Sectional with Chaise two methylbenzene planes and the 1,2-oxazole ring system.Intermolecular C—H.O and C—H.N hydrogen bonding and C—H.
π interactions stabilize the crystal structure.The H atoms of the two methyl groups of the methylphenyl groups are disordered over two positions with equal occupancies.
