In the title compound, C30H31NO2, the cyclohexanone ring in the naphthalene frondescence boise fused-ring system adopts a half-chair conformation, presumably due to conjugation of the benzene ring.The naphthalene ring system makes dihedral angles of 86.63 (7), 65.

15 (8) and 63.18 (8)° with respect to the two sal manaro knives 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.
