실험 절차

Dissolve 2-(S)-[bis-(2-methylbenzyl)-amino]-3-(3,5-difluorophenyl)-propan-1-ol (1.34 g, 3.38 mmol) in DMSO (3 mL) and cool in an ice bath. Add triethylamine (1.9 mL, 13.51 mmol) followed by sulfur trioxide-pyridine complex (1.07 g, 6.76 mmol). Stir 30 min then slowly add water (1.5 mL). Dilute with ethyl acetate and wash with 5% aqueous citric acid (3×), saturated aqueous sodium chloride, dry (magnesium sulfate) and concentrate to give the title compound as a light yellow residue.
