Procedure

The title compound was synthesized analogously to 83.8, using a solution of saccharin (92 mg, 0.5 mmol) in anhydrous DMF (4 mL), NaH (60% dispersion in mineral oil, 21 mg, 0.52 mmol) and a solution of 1-(4-bromobutoxy)-3-nitrobenzene (164 mg, 0.6 mmol) in anhydrous. DMF (1 mL). The crude product obtained after workup was purified by flash column chromatography on silica gel (25% ethyl acetate-petroleum ether) to give 83.9 as a white solid (m p 87-89° C.) in 55% yield (95 mg).
