Abstract
The pyrimidine ring of the title compound, C25H30N2O3, is approximately planar (r.m.s. deviation = 0.003 angstrom); the C atom at the 5-position deviates by 0.012 (3) angstrom from the mean plane and the C atom at the 6-position by 0.038 (3) angstrom. In the molecule, the pyrimidine ring is oriented at 86.72 (9) and 59.75 (9)degrees with respect to the two benzene rings, and the two benzene rings are inclined to each other at 58.35 (9)degrees. In the crystal, the amino group is hydrogen-bond donor to the exocyclic O atom at the 4-position of an adjacent molecule, the hydrogen bond generating an inversion dimer.
