In the title compound, C27H35N3O2, one of the pentyl side chains is ordered and the other is highly disordered [the occupancies for the major and minor components are 0.52 (1) and 0.48 (1), respectively]. The dihedral angles between the mean planes of the central C3N2 ring and the pendant phenyl and methoxy-benzene rings are 88.30 (17) and 9.08 (17)°, respectively. A weak intra-molecular C - H⋯N inter-action may help to establish the near planarity of the central and methoxyben...
