Versuchsvorschrift
To a solution of (S)-2-triphenylmethylamino-3-aminopropanol (1.99 g, 6 mmol) in CH2Cl2 (12 mL) at 0° C., triethylamine (1.7 mL, 12 mmol) was added dropwise followed by the addition of 4-phenoxybenzenesulfonyl chloride (1.61 g in 12 mL CH2Cl2). The reaction mixture was stirred at RT for 2 h and then was washed with water (20 mL) and brine (20 mL). The organic layer was dried over anhydrous Na2SO4, concentrated and purified through column chromatography (silica gel, 35% EtoAc in pet. ether) to afford (S)-3-(4-phenoxybenzenesulfonamido)-2-(tritylamino)propanol as colorless solid in 74% (2.52 g) yield.
