The six-membered oxacyclohexene ring of the title compound, C13H14N2O2S, is fused with the benzene ring and the quarternary C atom lies above the plane of the benzene ring by 0.229 (8) Å, whereas the methine C atom (which bears the acetyl substituent) lies below this plane by 0.595 (8) Å. The oxacyclohexene ring is also fused with the sofa-shaped 2,6-diazacyclohexanone ring. The methine C atom that belongs to both six-membered rings lies above the mean plane of the other five atoms (r.m.s. deviation = 0.077 Å) by 0.759 (5) Å. In the crystal, N—H⋯S hydrogen bonds link adjacent molecules into a linear chain.

In round-bottom flask that was fitted with a reflux condenser and a mechanical stirrer, salicylaldehyde (1.25 mol), acetylacetone (1.50 mol), thiocarbamide (1.25 mol), trichloroacetic acid (25 mg) and ethanol (10 ml) were reacted for 3 h. The solid that formed was collected and recrystallized from ethanol, m.p. 514–515 K; yield 80%.
Hydrogen atoms were placed in calculated positions [C–H 0.93 to 0.9 and N–H 0.88 7 Å; U(H) 1.2 to 1.5U(C,N)] and were included in the
in the riding model approximation.Data collection: APEX2 (Bruker, 2005); cell

The title compound, C13H14N2O2S (Scheme I, Fig. 1), is a conformationally restricted dihydropyrimidine analogue of 1,4-dihydropyridine-type calcium antagonists; the crystal structures of similar compounds have been reported (Kurbanova et al., 2009; Kettmann & Svetlík, 1996; Kettmann & Svetlík, 1997). Tthe six-membered oxacyclohexene ring that is fused with the benzene ring has the quarternary C atom lying above the plane of the benzene ring and the methine C (which bears the acetyl substituent) lying below this plane. The oxacyclohexene ring is also fused with the sofa-shaped diazacyclcohexane ring; the methine C that belongs to both six-membered rings lies above the mean plane of the other five atoms. Hydrogen bonds of the type N–H···S link adjacent molecules to form a linear chain (Fig. 2).
