Abstract
In the title compound, C14H15F3N2O5, prepared by reaction of 2-hydroxybenzaldehyde, ethyl 4,4,4-trifluoro-3-oxobutanoate and urea, the tetrapyrimidine ring adopts a half-chair conformation. The crystal structure is stabilized by five intermolecular 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.
