In the molecule of the title compound, C17H20FN3O4S, the pyrimidine and benzene rings are oriented at a dihedral angle of 35.59 (3)°. Intramolecular C—H⋯N and C—H⋯O hydrogen bonds result in the formation of one five- and two six-membered non-planar rings. One of the six-membered rings adopts a chair conformation, while the other six-membered ring and the five-membered ring exhibit envelope conformations with O and N atoms displaced by 0.837 (3) and 0.152 (3) Å, respectively from the planes of the other ring atoms. In the intermolecular C—H⋯F hydrogen bonds link the molecules into infinite chains.

For the preparation of the title compound, sodium salt of N-methyl methane sulphonamide (106 g, 631.00 mmol) and methyl 4-(4-fluorophenyl)-6-isopropyl- 2-methyl sulfonylpyrimidine-5-carboxylate (100 g, 284.06 mmol) were added to DMF (1000 ml) in a round bottom flask, and then stirred for 1 h at 303 K. After completion of the reaction, demineralized water (1000 ml) was added and stirred for 1 h. The mixture was filtered, washed with water, and then dried (yield; 95%). Crystals of (I) suitable for X-ray analysis were obtained by slow evaporation of an ethanol solution.
H atoms were positioned geometrically, with C-H = 0.93, 0.98 and 0.96 Å for aromatic, methine and methyl H, respectively, and constrained to ride on their parent atoms with Uiso(H) = xUeq(C), where x = 1.5 for methyl H, and x = 1.2 for all other H atoms.

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 > 2sigma(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. |

Some derivatives of pyrimidine are important chemical materials. We report herein the crystal structure of the title compound, (I).
In the molecule of (I), (Fig. 1), rings A (N1/N2/C4-C7) and B (C12-C17) are, of course, planar, and the dihedral angle between them is A/B = 35.59 (3)°. The intramolecular C-H···N and C-H···O hydrogen bonds (Table 1) result in the formation of one five- and two six-membered non-planar rings: C (N2/N3/C5/C11/H11A), D (S/N1/N3/C5/C10/H10B) and E (O1/C3/C4/C7/C8/H3B), respectively. Ring D adopts chair [ϕ = -40.04 (2)° and θ = 134.72 (3)°] conformation, having total puckering amplitude, QT, of 1.188 (3) Å (Cremer & Pople, 1975). Rings C and E have envelope conformations with nitrogen and oxygen atoms displaced by 0.152 (3) Å and 0.837 (3) Å from the planes of the other ring atoms, respectively.
In the crystal structure, intermolecular C-H···F hydrogen bonds (Table 1) link the molecules into infinite chains (Fig. 2), in which they may be effective in the stabilization of the structure.
