In the title compound, C(11)H(14)N(2)O(2), the urea-type NC=ON moiety [planar to within 0.0002 (13) Å] is inclined to the phenyl ring by 42.88 (8) Å, and the morpholine ring has a chair conformation. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into infinite chains in [001].
