Versuchsvorschrift

To a solution of (5R,9R)-9-(dodecanoyloxy)-1-(9H-fluoren-9-yl)-3,12-dioxo-2,11-dioxa-7-thia-4-azatricosane-5-carboxylic acid (6, 1 eq) in DMF (0.2 M) was added DIEA (5 eq) and EDCI (1.3 eq) and HOBT (1.3 eq). The reaction was stirred at room temperature for 10 minutes, which was followed by adding benzyl 6-aminohexanoate hydrochloride (1.2 eq). The reaction mixture was then stirred at room temperature overnight. The mixture was diluted with ethyl acetate, and washed with saturated NaHCO3 solution, water and brine. The organic layer was dried over anhydrous Na2SO4, and concentrated en vaccuo. The crude mixture was purified by flash chromatography on a COMBIFLASH® system (ISCO) using 0-5% MeOH/DCM to give the title product.
