In the title compound, C15H16N2O2S, the dihedral angle between the 4-methoxyaniline and 2-aminobenzenethiole fragments is 35.60 (9)°. A short intramolecular N—H⋯S contact leads to an S(5) ring. In the crystal, molecules are consolidated in the form of polymeric chains along [010] as a result of N—H⋯O hydrogen bonds, which generate R32(18) and R43(22) loops. The polymeric chains are interlinked through C—H⋯O interaction and complete R22(8) ring motifs.

2-Aminobenzothiol (0.125 g, 0.5 mmol) was dissolved in anhydrous diethylether (10 ml) and NaH (0.024 g, 1 mmol) was added to it at temperature 273–278 K. A separately prepared solution of 2-chloro-N-(4-methoxyphenyl)acetamide (0.1 g, 0.5 mmol) in anhydrous diethylether (10 ml) was added drop wise to above mixture. The mixture was stirred for 4 h and solvent was evaporated to get greyish crystals of (I). m.p. 400 K
The H-atoms were positioned geometrically (N—H = 0.86, C–H = 0.93–0.97 Å) and were included in the
in the riding model approximation, with Uiso(H) = xUeq(C, N), where x = 1.5 for CH3 and x = 1.2 for other H-atoms.Data collection: APEX2 (Bruker, 2009); cell

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The title compound (I), (Fig. 1) has been synthesized to check its biological application as antimicrobial agent owing to the concept that amide moiety is an important part of different drugs.
The crystal structure of N-(4-methoxyphenyl)acetamide (Haisa et al., 1980) has been published which is related to the title compound (I, Fig. 1).
In (I), the 4-methoxyanilinic and 2-aminobenzenethiolic groups A (C1–C7/N1/O1) and B (C10—C15/N2/S1) are almost planar with r. m. s. deviation of 0.0150 Å and 0.0134 Å, respectively. The dihedral angle between A/B is 35.60 (9)°. The central acetamide moiety C (C8/C9/O2) is of course planar. The dihedral angle between A/C and B/C is 48.43 (10)° and 78.07 (8)°, respectively. There exist S(5) ring motif (Bernstein et al., 1995) due to H-bonding of N—H···S type (Table 1, Fig. 2). The molecules are stabilized in the form of one-dimensional polymeric network due to H-bondings (Table 1, Fig. 2) of N—H···O type. There exist R32(18) and R43(22) ring motifs in the polymeric network when three and four molecules respectively, are connected with each other.
