چکیده
In the title compound, C(14)H(15)F(3)N(2)O(5), prepared by reaction of 2-hy-droxy-benzaldehyde, ethyl 4,4,4-trifluoro-3-oxobutano-ate and urea, the tetra-pyrimidine ring adopts a half-chair conformation. The crystal structure is stabilized by five inter-molecular hydrogen bonds, three O-H⋯O and two N-H⋯O, giving cyclic dimers (through three hydrogen bonds) which are further extended into a two-dimensional network.
