%X In the title compound, C29H27N3O4S¡¤0.5C6H14, the heterocyclic thiazine ring adopts a half-chair conformation with the S and N atoms displaced by 0.500 (5) and 0.229 (5)  , respectively, on opposite sides from the mean plane formed by the remaining ring atoms. The mean planes of the pyrazole ring and the benzene ring bonded to it form a dihedral angle of 35.76 (11)¡ã and an intramolecular O¡ªH...O hydrogen bond ocurs. The crystal structure features O¡ªH...O and C¡ªH...O hydrogen bonds. There is a half-molecule of hexane in the asymmetric unit lying about an inversion center. It is disordered over two sets of sites with occupancy factors 0.590 (9) and 0.410 (9).
