3-tert-Butyl-4-(4-chloro­phen­yl)-1-phenyl-1H-pyrazolo­[3,4-e][1,4]thia­zepin-7(4H,6H,8H)-one

In the title mol­ecule, C22H22ClN3OS, the fused 1,4-thia­zepinone ring adopts a near twist-boat conformation and the chloro­benzene ring is inclined to the phenyl ring by 88.38 (12)°. In the crystal, mol­ecules are linked by pairs of N—H⋯O hydrogen bonds, forming inversion dimers with an R22(8) ring motif. The dimers are linked via C—H⋯O hydrogen bonds forming ribbons, enclosing R42(20) loops, propagating along [001].
