(E)-tert-Butyl 2-(5-{[4-(dimethylamino)phenyl]diazenyl}-2,6-dioxo-1H-pyrimid­in-3-yl)acetate dichloromethane monosolvate

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 an R²₂(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.
