Reaktionsschritte
6-Bromohexanoic Acid (10.0 g, 0.051 mol), benzyl alcohol (6.1 g, 0.056 mol) and DMAP (dimethylaminopyridine, 0.63 g, 0.005 mol) were dissolved in 100 mL CH2Cl2, then cooled to 0° C. 1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC, 10.8 g, 0.056 mol) was added and the reaction stirred overnight at room temperature. The organics were diluted with CH2Cl2 and washed with water, aq. NaHCO3, and brine. The organic phase was dried (Na2SO4), filtered, and solvent was removed. Intermediate 12 was obtained as a colorless oil (11.6 g, 0.04 mol). MS(MH+): m/z=286.
