2-(4-methylsulfanylbutyl)isoindole-1,3-dione

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A solution of 2-(4-bromo-butyl)-isoindole-1,3-dione (1.00 g, 3.54 mmol) in MeOH (60 mL) was treated with sodium thiomethoxide (0.298 g, 4.25 mmol) and heated to reflux 18 h. The solvent was evaporated in vacuo and the residue partitioned between EtOAc and water. The aqueous layer was further extracted with EtOAc (1×75 mL). The organic layers were dried over MgSO4 and concentrated in vacuo to afford the product 2-(4-methylsulfanyl-butyl)-isoindole-1,3-dione (0.803 g, 91%). 1H NMR (MeOD) 7.844 (m, 4H), 3.704 (t, 2H, J=7.2 Hz), 2.549 (t, 2H, J=7.2 Hz), 2.063 (s, 3H), 1.792 (quint, 2H, J=7.2 Hz), 1.731 (quint, 2H, J=7.2 Hz). heated to reflux 18 h The solvent was evaporated in vacuo the residue partitioned between EtOAc and water The aqueous layer was further extracted with EtOAc (1×75 mL) The organic layers were dried over MgSO4 concentrated in vacuo
