Procedure

A solution of 4-nitrobenzenethiol (Aldrich, 2.5 g; 16.1 mmol) in acetone (110 ml) was treated with potassium carbonate (2.22 g; 16.1 mmol) and ethyl 4-bromobutanoate (Aldrich, 3.43 g; 17.6 mmol). After stirring at RT for 18 hours, the mixture was filtered and the solid washed with acetone. The organic fractions were combined and the solvent removed in vacuo. The residue was purified by column chromatography (silica) eluting with petroleum ether containing increasing amounts of Et2O to give the title compound as an off-white solid (4.0 g, 92%).
