Procedure

To a solution of compound 9-C (0.100 g, 0.300 mmol) in DMF (5 mL) at room temperature was added 60% NaH (0.012 g, 0.300 mmol) and the reaction mixture was stirred for 10 minutes. Benzenesulfonyl chloride (0.053 g, 0.300 mmol) was added and the reaction mixture was stirred at room temperature overnight. DMF was removed in vacuo and water and methylene chloride were added. The organic layer was washed with H2O (2×), brine, dried over Na2SO4, filtered, and the solvent evaporated under reduced pressure to afford the crude product. The crude material was purified by flash column chromatography (SiO2) eluting with a gradient of 0-100% ethyl acetate in hexane to afford compound 9-D (0.040 g, 28%); MS m/z (M+H+) 476.
