Reaction Steps

To a solution of 4-chloro-N-[5-chloro-2-(acetoxymethyl)phenyl}-N-[(R)-1-methyl-4-bromobutyl]benzenesulfonamide (1.00 g, 1.91 mmol) in DMF (4 mL) was added sodium thioethoxide (0.535 g, 7.63 mmol) under nitrogen at 0° C. The mixture was stirred overnight at 22° C. The mixture was quenched with H2O (3 mL), extracted with ethyl ether (2×20 mL), dried over Na2SO4, and filtered. The organic solvent was concentrated under reduced pressure. Silica gel chromatography (1:9 ethyl acetate:hexanes) afforded 0.123 g of 4-ethylthio-N-[5-chloro-2-(hydroxymethyl)phenyl]-N-[4-(ethylthio)]-1-(R)-methylbutyl]benzenesulfonamide as a yellow oil in 14% yield. MS (ESI+), 488 (M+H)+.
