The title compound, C13H14ClN5O, was synthesized from 2,4-dichloro-6-morpholino-1,3,5-triazine and aniline. In the crystal structure, there are intermolecular N—H
O hydrogen bonds which propagate infinite chains parallel to the c axis. The morpholine ring adopts a chair conformation.

In the title molecule, C21H15NO, the two ethynyl-bridged six-membered rings are almost coplanar, making a dihedral angle of 3.3 (2)°. The dihedral angle between the two terminal phenyl rings is 62.9 (2)°. The crystal packing is stabilized by weak intermolecular N—HO hydrogen bonds.

The structure of the title compound, C13H10O4, which was synthesized by the reaction of salicylaldehyde and 4-hydroxy-6-methyl-2H-pyran-2-one in the presence of triethylbenzylammonium chloride in aqueous media, was previously determined at room temperature [March, Moreno-Manas, Roca, Germain, Piniella & Dideberg (1986). J. Heterocycl. Chem. 23, 1511–1153]. As in the present determination, the X-ray analysis revealed that the title compound is in the enol form, which was confirmed by 1H NMR data. Weak intermolecular C—HO interactions connect molecules into a two-dimensional framework.
