In the title compound, C18H23N5O4·CH2Cl2, the dichloromethane solvent molecule is disordered over two sets of sites in a 0.630 (13):0.370 (13) ratio. The dihedral angle between the uracil and phenyl rings is 30.2 (1)°. In the crystal, the principal interactions are N—H...O hydrogen bonds, which link uracil units across centres of symmetry, forming eight-membered rings with anR22(8) graph-set motif. The structure also displays C—H...O and C—H...Cl hydrogen bonds. Intramolecular C—H...O short contacts are also observed.

The title compound, C31H39NO, was prepared by the condensation of 5-tert-butyl-2-hydroxy-3-(1-phenylethyl)benzaldehyde with 2,6-diisopropylphenylamine in refluxing ethanol. The phenol ring and the phenylimino ring are approximately perpendicular, forming a dihedral angle of 81.5 (3)°. The phenyl ring makes a dihedral angle of 75.2 (2)° with the phenol ring and also makes a dihedral angle of 62.9 (3)° with the phenylimino ring. The molecular structure is stabilized by an intramolecular O—H...N hydrogen bond linking the phenol OH group and the phenylimino N atom. One of the isopropyl groups is disordered over two positions; the site occupancies are 0.55 and 0.45.
