摘要

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 R ² 2(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.
