반응 단계
A solution of N-(3-Dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (5.7 g) in dichloromethane (100 ml) was slowly added to a solution of 8-chloro-1-octanol (4.1 g), tetrahydro-2-furancarboxylic acid (3.5 g) and 4-dimethylaminopyridine (1.5 g) in dichloromethane (50 ml) at 0° C. The mixture was stirred overnight at room temperature. The resulting solution was then added to water (500 ml) and extracted with dichloromethane (3×200 ml). The combined organic layers were washed with water (2×200 ml), dried over magnesium sulphate and filtered. The solvent removed in vacuum. The residue (7 g) was purified by column flash chromatography on silica gel using toluene/ethyl acetate (90:10) as eluent to give 8-chlorooctyl tetrahydro-2-furancarboxylate.
