Procedure

To a solution of 4-chloro-N-(2,5-difluorophenyl)-N-[(R)-1-methyl-4-bromobutyl]-benzenesulfonamide (0.505 g, 1.12 mmol) in THF/H2O (8/2, 10 mL) was added sodium azide (0.363 g, 5.58 mmol) at 22° C. The resulting mixture was allowed to stir at 22° C. for 10 days. The mixture was extracted with ether (3×20 mL). The combined organic extracts were washed with sat. NaHCO3, dried over MgSO4, filtered, and concentrated under reduced pressure. Silica gel chromatography (1:9 ethyl acetate:hexanes) of the concentrate afforded 0.455 g of 4-chloro-N-(2,5-difluorophenyl)-N-[(R)-1-methyl-4-azidobutyl]benzenesulfonamide as a colorless oil in 98% yield.
