Source of material
To a mixture of 2-(4-((1,3-dioxoisoindolin-2-yl)methyl)phenyl)ethyl-4-methylbenzenesulfonate (217.8 mg, 0.5 mmol) in 50 mL EtOH and KOH (112.2 mg, 2.0 mmol), 1-benzylpiperazine (96.9 mg, 0.55 mmol) was added at ambient temperature. The reaction mixture was stirred and heated to reflux for 2–3 h, until TLC indicated the end of reaction. Solvent was removed under reduced pressure, and the residue was extracted with CH2Cl2 (100 mL, 3 times). The combined organic layer was successively washed with water, brine, dried over anhydrous sodium sulfate, and concentrated in vacuo. The residue was purified by silica gel column chromatography using ethyl acetate/petroleum ether (1:8, v/v) as eluent, to afford the title compound as a white solid.
Experimental details
The structure was solved with SHELXT [1] and refined with SHELXL [1]. All H atoms were placed in geometrically idealized positions and refined using a riding model, with C—H = 0.97 (methylene), 0.93 Å (benzene), and with Uiso(H) = 1.2Ueq(C) for H atoms on methylene and benzene.
Comment
The arylpiperazine moiety as an important pharmacophore is widely used to generate pharmacological activities [3], [4], [5]. Arylpiperazine derivatives referred to in this paper possess antitumor activity. The asymmetric unit contains only one independent molecule.
The title compound contains three aryl rings, a piperanzinyl and a pyrrole moiety. Ring (C23—C28) and ring (C21—N3—C22—C23—C28) are coplanar. The dihedral angles made by the planes of the ring (C1—C6) and ring (N1—C8—C11—N2—C10—C9), ring (C1—C6) and ring (C15—C19), ring (C1—C6) and ring (C23—C28) are 52.25(8)°, 104.97(8)° and 66.35(8)°, respectively. The packing structure shows some weak non-classical hydrogen bonds.
