6-(3,5-Dimethyl-benz-yl)-5-ethyl-1-[(2-phenyl-eth-oxy)meth-yl]pyrimidine-2,4(1H,3H)dione.

ABSTRACT: In the title pyrimidine derivative, C(24)H(28)N(2)O(3), the uracil unit is essentially planar with an r.m.s. deviation of 0.0054 (1) Å for the eight non-H atoms. The pyrimidine ring is tilted by a dihedral angle of 77.08 (7)° with respect to the aromatic ring of the 3,5-dimethyl-benzyl substituent, whereas it is nearly parallel to the benzene ring of the pheneth-oxy-methyl unit, with a dihedral angle of 8.17 (8)°. An intra-molecular C-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked by a pair of amide-uracil N-H⋯O hydrogen bonds into an inversion R(2) (2)(8) dimer. These dimers are stacked along the b axis through π-π inter-actions with a centroid-centroid distance of 3.9517 (8) Å. Weak C-H⋯π inter-actions are also present.
