2-(3,4-Dimethyl-5,5-dioxo-2H,4H-pyrazolo-[4,3-c][1,2]benzothia-zin-2-yl)-N-(2-fluoro-benz-yl)acetamide.

ABSTRACT: In the title mol-ecule, C(20)H(19)FN(4)O(3)S, the heterocyclic thia-zine ring adopts a half-chair conformation with the S atom displaced by 0.668 (4) Å from the mean plane formed by the remaining ring atoms. The mean planes of the benzene and pyrazole rings are inclined with respect to each other at a dihedral angle of 17.4 (3)°. The acetamide chain (O/N/C/C/C) linking the pyrazole and 2-fluoro-benzyl rings is essentially planar (r.m.s. deviation = 0.030 Å) and forms dihedral angles with the mean planes of these rings of 78.8 (2) and 78.89 (14)°, respectively. The crystal structure is stabilized by N-H⋯O and C-H⋯O hydrogen-bonding inter-actions, resulting in a six-membered ring with an R(2) (1)(6) motif, while C-H⋯O and C-H⋯F hydrogen-bonding inter-actions result in chains of mol-ecules lying along the c axis in a zigzag fashion.

Project description:The asymmetric unit of the title compound, C(21)H(22)N(4)O(4)S, contains two mol-ecules (A and B), in which the thia-zine rings adopt an S-envelope conformation with the S atoms displaced by 0.621?(2) and 0.697?(2)?Å from the mean planes formed by the remaining ring atoms.

In the crystal, N-H?O hydrogen bonds connect the components into C(4) [100] chains of alternating A and B mol-ecules. The packing is consolidated by weak C-H?O inter-actions, which generate a three-dimensional network.
