Abstract

The title heterocyclic compound, C(17)H(23)N(3)O(2)S, was synthesized from 4-(4-methyl-cyclo-hex-3-en-yl)pent-3-en-2-one, which was isolated from Cedrus atlantica essential oil. The thia-diazole ring adopts a flattened envelope conformation, with the flap sp(3)-hybridized C atom lying 0.259 (1) Å out of the plane of the other four atoms. The screw-related mol-ecules are linked into chains along the b axis by inter-molecular N-H⋯O hydrogen bonds.
