In the title compound, C 18H 19N 3O 5, the 3,6-dihydro-2H-pyran ring adopts a half-chair, distorted towards a half-boat, conformation with Q T = 0.5276(14) Å. The benzene ring is twisted out of the place of the triazole ring [dihedral angle = 23.54 (8)°]. In the crystal, supramolecular layers in the ac plane are formed through C-H⋯O and C-H⋯π(triazole) interactions. These stack along the b axis being connected by C-H⋯N contacts.
