Versuchsvorschrift

The propanolamine compound prepared above (1.0 eq), N-(benzyloxycarbonyl)ethanolamine (25 eq) and camphorsulfonic acid (1.0 eq) are dissolved in a small amount of dioxane-DMF-DMSO (10:2:1) and stirred at room temperature for about 24 hours. The mixture is neutralized by the addition of aqueous sodium bicarbonate and purified by preparative HPLC (C18 “ZORBAX”, step gradient starting at 70/30:H2O/CH3CN/0.1% TFA). The appropriate fractions are combined, frozen and lyophilized to give solid (MW=1621.66).
