A solution of N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (4.8 g) in dichloromethane (60 ml) was slowly added to a solution of 8-(2-furylmethoxy)-8-oxooctyl 2,5-dihydroxybenzoate (3.7 g), 4-(6-acryloylhexyloxy)benzoic acid (7.3 g) and 4-dimethylaminopyridine (0.6 g) in dichloromethane (150 ml) at 0° C. The mixture was stirred overnight at room temperature. The resulting solution was then added to water (600 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 (10.4 g) was purified by column flash chromatography on silica gel using toluene/ethyl acetate (95:5) as eluent, to give 8-(2-furylmethoxy)-8-oxooctyl 2,5-bis[(4-{[6-(acryloyloxy)hexyl]oxy}benzoyl)oxy]benzoate.
