title: 1-Benzyl-3-phenyl-quinoxalin-2(1H)-one.
abstract: The ten-membered fused ring system in the title compound, C(21)H(16)N(2)O(2), is planar (r.m.s. deviation = 0.03 Å). The phenyl substituent is aligned at 15.1 (1)° with respect to the mean plane through this system, whereas the phenyl ring of the benzyl substitutent is aligned at 84.4 (1)°.
