Reaction Steps

To a solution of 4-chloro-N-(5-chloro-2-fluorophenyl)-N-[(R)-1-methyl-3-azidopropyl]-benzenesulfonamide (1.34 g, 3.27 mmol) in THF (32 mL) was added lithium aluminum hydride (6.53 mL, 1 M in THF) at 0° C. under nitrogen atmosphere. The resulting mixture was allowed to stir at 0° C. for 1 h and subsequently treated by successive dropwise addition of 0.248 mL of water, 0.248 mL of 15% sodium hydroxide solution, and 0.744 mL of water. The mixture was filtered and concentrated under reduced pressure. Silica gel chromatography (3:10 ethyl acetate:hexanes) of the concentrate afforded 1.12 g of 4-chloro-N-(5-chloro-2-fluorophenyl)-N-[(R)-1-methyl-3-aminopropyl]benzenesulfonamide as a light brown oil in 85% yield.
