A mixture of N-(4-methoxy-2-nitrophenyl)methane sulfonamide (2.462507 g; 10.0 mmoles) and acetic anhydride (10.0 ml) was heated to reflux for half an hour and then poued over crushed ice. Resultant solids were then washed with cold water and dried under reduced pressure. Yellow crystals were obtained by slow evaporation of an ethanolic solution over a period of two days.
H atoms bound to C were placed in geometric positions (C—H distance = 0.93 to 0.96 Å) using a riding model with Uiso(H) = 1.2 Ueq(C) or Uiso(H) = 1.5 Ueq(Cmethyl).

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

N-(Substituted phenyl)acetamides are considered as important intermediates in organic synthesis. A large number of heterocyclic compounds such as 2,5-piperazinedione (Wen et al., 2006), (quinolin-8-yloxy) acetamide (Zhang et al., 2006) and 2,2-(1,3,4-thiadiazolyl-2,5-dithio)diacetamide (Wen et al., 2005) are being efficiently synthesized starting from such acetamides. In the present paper, the structure of N-(4-Methoxy-2-nitrophenyl)-N-(methylsulfonyl)acetamide has been determined as part of a research program involving the synthesis and biological evaluation of sulfur containing heterocyclic compounds (Siddiqui et al., 2007).
In the molecule (Fig. 1), the bond lengths and bond angles are similar to those in the related molecules (Wen et al., 2006; Zhang et al., 2006) and are within in normal ranges. The nitro group is slightly twisted out of the plane of the aromatic ring. Each molecule is linked to its neighbour by inter molecular C—H···O interactions forming a chain along the a axis (Table 1 and Fig. 2).
