title: 1-(4-tert-Butyl-benz-yl)pyrimidine-2,4(1H,3H)-dione.
abstract: The asymmetric unit of the title compound, C(15)H(18)N(2)O(2), contains two independent mol-ecules with essentially identical geometries and conformations. The dihedral angles between the benzene and pyrimidine rings in the two mol-ecules are 89.96 (11) and 73.91 (11)°. The six methyl groups are disordered over two sets of sites, with site occupancies of 0.545 (4):0.455 (4) and 0.542 (7):0.458 (7) in the two mol-ecules. The crystal structure is stabilized by N-H⋯O hydrogen bonds.
