title: 2-[(4,6-Dimeth-oxy-pyrimidin-2-yl)-oxy]benzaldehyde.
abstract: In the title compound, C(13)H(12)N(2)O(4), the dihedral angle between the benzene and pyrimidine rings is 55.57 (13)°. The carbonyl group and the two methoxyl groups are approximately coplanar with the benzene ring and pyrimidine ring; the C-C-C-O, C-O-C-N and C-O-C-C torsion angles being -6.1 (5), -4.8 (4) and 179.9 (3)°, respectively. In the crystal, mol-ecules are linked via C-H⋯O inter-actions, forming chains propagating along [110].
