Procedure

(S)-(6-Hydroxy-5-isobutylamino-hexyl)-carbamic acid tert-butyl ester (4) (1.85 g) was dissolved in 50 mL CH2Cl2. Triethylamine (1.05 eq) and 4-cyano benzene sulfonylchloride (1 eq) were added and the mixture was stirred overnight. Saturated NaHCO3 (50 mL) was added, the mixture was well shaken. Organic layer was separated, dried on MgSO4, filtrated and evaporated. The crude compound was purified by column chromatography using EtOAc-heptane (1-3) as the eluent. Fractions containing the product were evaporated yielding (1.06 g, 36%) of a solid.
