실험 절차

A solution of N,N-dicyclohexylcarbodiimide (0.18 g, 0.8 mmol) in dichloromethane (10 cm3) is added to a solution of (E)-hex-2-enoic acid (0.07 g, 0.7 mmol), 1-[4-(trans-5-hydroxydioxan-2-yl) phenyl]-4-pentylbicyclo[2.2.2]octane (0.25 g, 0.7 mmol), 4-(dimethylamino) pyridine (0.04 g) in dichloromethane (20 cm3), cooled in an ice bath (0° C.) under an atmosphere of nitrogen. The reaction mixture is stirred overnight, filtered to remove precipitated material and the filtrate was evaporated down under reduced pressure. The crude product is purified by column chromatography on silica gel using a 9:1 petroleum ether (40-60° C.)/ethyl acetate mixture as eluent, followed by recrystallisation from ethanol to yield the desired ester.
