Abstract
The title compound, C22H20N4O3S, features two fused six-membered rings linked to a 1,2,3-triazole ring which is attached to an ethyl acetate group. The heterocycle in the benzothiazine residue has an envelope conformation with the S atom being the flap. The conformation of the ethyl acetate side chain, which is directed to the same side of the molecule as the C6 ring of the fused-ring system, may be partially established by a pair of weak intramolecular C—H⋯O(carbonyl) interactions. The three-dimensional packing is aided by intermolecular C—H⋯O and C—H⋯N interactions.
