The title compound, ethyl 3-(9-anthryl)-5-methyl-4-isoxazolecarboxylate, C21H17NO3, possesses two planar ring systems that lie at 80° from coplanarity. The bond linking the two ring systems is 1.489 (3) Å, indicating only partial conjugation between the two ring systems. The resulting distortion causes large upfield NMR chemical shifts in the ethyl ester, which lies directly underneath the anthracene ring.
