Reaction Steps

To a solution of 4-chloro-N-[5-chloro-2-(acetoxymethyl)phenyl]-N-[(R)-1-methyl-4-bromobutyl-benzenesulfonamide (0.650 g, 1.24 mmol) in tetrahydrofuran (2 mL) was added sodium thioethoxide (0.115 g, 1.36 mmol) under nitrogen at 0° C. The mixture was stirred overnight at 22° C. The mixture was quenched with 2M NaOH (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 0.500 g of 4-chloro-N-[5-chloro-2-(hydroxymethyl)phenyl]-N-[4-(ethylthio)]-1-(R)-methylbutyl]benzenesulfonamide as a yellow oil in 87% yield. MS (ESI+), 462 (M+H)+.
