Abstract
In the title compound, C24H25N3S2, the S-bound benzene rings have orthogonal [dihedral angle = 85.31 (9)degrees] and splayed [67.92 (11)degrees] orientations with respect to the pyrimidine ring; the dihedral angle between the benzene rings is 48.18 (12)degrees. The pentyl group has an extended all-trans conformation and lies to one side of the pyrimidine ring [the N-py-C-py-C-p-C-p torsion angle = -85.7 (2)degrees; py = pyrimidine and p = pentyl].
