A 25 mL round bottom flask charged with 2.5 mL of H2O, 2.5 mL ethanol and 0.1499 g (1.26 mmol) of 4,4-dimethyl-3-thiosemicarbazide was dissolved in a water/ethanol mixture and heated. Once the mixture was completely dissolved, 0.2225 g (1.34 mmol) of 2'-hydroxy-5'-methoxyacetophenone was added, and the solution was refluxed for 18 hours resulting in the formation of a yellow solid. After reflux, the slurry was allowed to cool to room temperature, transferred to a separatory funnel and water (15 mL) and dichloromethane (15 mL) was added. The organic layer was separated and the aqueous layer was extracted with an additional 15 mL of DCM. The organic layers were then combined and washed with brine (20 mL), and then dried with magnesium sulfate. The solvent was removed by rotary evaporation. The resulting solid was crystallized from acetonitrile to give 67 mg (18% yield) of yellow crystals. The crystals were observed to decompose above 460 K.
Crystal data, data collection and structure refinement details are summarized in Table 1. All H atoms were located in difference maps. The C–H and N–H atoms were treated as riding atoms in geometrically idealized positions with C—H, N—H distances of 0.95 Å, 0.88 Å and refined with Uiso(H) = 1.2Ueq(C, N). The CH3 and O–H atoms were also treated as riding atoms in geometrically idealized positions with the CH3, O—H distances of 0.98 Å, 0.84 Å and refined with Uiso(H) = 1.5Ueq(C, O).
The asymmetric unit of the title compound, C12H17N3O2S, contains two independent molecules A and B, respectively (Fig. 1). Both molecules are nearly planar with the dihedral angle between the mean planes of the thioamide group and benzene ring being 7.5 (1)° in A and 4.3 (2)° in B. In each molecule, the hydroxy group participates in intramolecular O—H···N hydrogen bonding, while the amino H atom is not involved in hydrogen bonding because of the steric hinderence caused by two neighboring methyl groups. In the crystal, weak intermolecular C—H···O and C—H···π (Table 1) interactions are observed which help stabilize the packing (Fig. 2). No π—π stacking interactions are present.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |

The asymmetric unit of the title compound, C12H17N3O2S, contains two independent molecules A and B, respectively (Fig. 1). Both molecules are nearly planar with the dihedral angle between the mean planes of the thioamide group and benzene ring being 7.5 (1)° in A and 4.3 (2)° in B. In each molecule, the hydroxy group participates in intramolecular O—H···N hydrogen bonding, while the amino H atom is not involved in hydrogen bonding because of the steric hinderence caused by two neighboring methyl groups. In the crystal, weak intermolecular C—H···O and C—H···π (Table 1) interactions are observed which help stabilize the packing (Fig. 2). No π—π stacking interactions are present.
