Abstract: The title heterocyclic compound, C₂₀H₂₇N₃O₂S, was synthesized from 2-(4-methylcyclohex-3-enyl)-6-methylhepta-2,5-dien-4-one, which was isolated from the essential oil Cedrus atlantica. The thiadiazole ring is essentially planar [maximum deviation 0.006 (2) Å] and it forms a dihedral angle of 18.08 (9)° with the benzene ring. The dihedral angle between the thiadiazole ring and the acetamide plane is 7.62 (10)°. In the crystal, molecules are linked into chains running along the c axis by intermolecular N-HO hydrogen bonds.
