title: 7-(Benzyl-sulfan-yl)-5-(2-methoxy-phen-yl)-1,3-dimethyl-5,6-dihydro-pyrimido[4,5-d]pyrimidine-2,4(1H,3H)-dione.
abstract: In the mol-ecule of the title compound, C(22)H(22)N(4)O(3)S, the benzene and phenyl rings are oriented at a dihedral angle of 88.72 (4)°. The other two rings have flattened-boat conformations. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules.
