Abstract

There are two mol­ecules, A and B, in the asymmetric unit of the title compound, C14H16N2O4S, which is the first example reported in this family of compounds in which the Nsp 3 atom of the thia­diazine ring is methyl­ated. The thia­diazine rings adopt shallow envelope conformations, with the S atoms displaced by 0.319 (12) and 0.182 (12) Å from the mean planes of the other ring atoms in mol­ecules A and B, respectively. The dihedral angles between the thia­diazine mean planes (excluding S) and the attached benzene rings are 86.8 (3) and 86.7 (3)° for mol­ecules A and B, respectively.

Comment

The synthesis of 1,2,6-thiadiazine-1,1-dioxides derivatives was first reported using sulfamide with alpha and beta diketones (Wright, 1964). We have reported the 3,5-dimethyl based structure with an aromatic ring at position 4 of the thiadiazine ring containing an ethyl ester functional group (Bhatt et al., 2012). The structure displayed intermolecular hydrogen bonding.

The title compound is also a 3,5 dimethyl based structure with an aromatic ring at the same position on the thiadiazine ring, but here the sp3 nitrogen atom is methylated. This prevents any equivalent hydrogen bonding features in the structure seen in previous examples. The is no π-π stacking or weak CH—π inteactions either in the crystal. The title compound has two isomeric forms in the crystal. The sulfur atoms S1A and S1B deviate from their ring planes (N1A/B, C2/AB, C3A/B, C4A/B, N2A/B) by 0.319 (12) Å and 0.182 (12) Å respectively (Fig. 1) and the benzene rings deviate from the planes by 86.8 (3) and 86.7 (3)°, respectively. The ester functional groups of the two isomers are not co-planar to the benzene ring planes but differ by 16.93 (4) and 16.48 (4)°, respectively.

Experimental

2-(3, 5-dimethyl-1, 1-dioxo-2H-1, 2, 6-thiadiazin-4-yl) benzoic acid (4.75 g,17 mmole) was dissolved in acetone (125 ml), to this K2CO3 (11.75 g, 85 mmole) was added slowly and then stirred for 10–15 min. Methyl iodide (7.23 g, 51 mmole) was added and reaction mixture was refluxed for 3 hrs. The reaction progress was monitored by TLC using ethyl acetate/hexane (8:2,Rf = 0.8). Excess solvent was completely evaporated under vacuum. The residue was treated with conc.HCl to get 2-(2,3,5-trimethyl-1,1-dioxido-2H-1,2,6-thiadiazin-4-yl)benzoic acid as a white solid (4.3 g Yield: 81.9%).

2-(2,3,5-trimethyl-1,1-dioxido-2H-1,2,6-thiadiazin-4-yl)benzoic acid (2.94 g, 10 mmole) was dissolved in methanol (25 ml), to this solution thionyl chloride (5.95 g, 50 mmole) was added slowly and the reaction mixture was refluxed for 3 hrs. The reaction progress was monitored by TLC using ethyl acetate/hexane (8:2,Rf = 0.8). Excess solvent was completely evaporated under vacuum. The residue was purified by silica gel column using methanol/ethyl acetate (1:9) as the eluent to afford the methyl ester as a colourless solid. (1.34 g,Yield: 55%).M.p.= 260 K

Recrystallization using dioxane/water at room temperature afforded yellow blocks.

Refinement

All hydrogen atoms were placed in idealized positions and refined with geometrical constraints. Flack x parameter is -0.0586 with e.s.d. 0.0543.

Special details

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.
