Abstract

In the title compound, C21H22ClN3O6S, the fused five- and six-membered ring rings are almost perpendicular to the planes through the atoms forming the acetyl and the propionic ester groups, as indicated by the dihedral angles of 80.3 (2) and 88.3 (7)°, respectively. The dihedral angle between the indazole system and the 4-meth-oxy-benzene-sulfonyl group is 13.76 (6)°. The carbonyl O atom is split over two positions in a 0.60 (5):0.40 (5) ratio. In the crystal, mol-ecules are linked by C-H⋯O and C-H⋯N inter-actions into a three-dimensional network.
