실험 절차

4.73 g (10 mmol) of (1R)-1-benzyloxycarbonylmethyl-2-(5-cyano-2-iodophenoxy)ethylammonium chloride, 2.9 g (20 mmol) of 4-cyanobenzoic acid, 3.0 g (22 mmol) of 1-hydroxybenzotriazole and 6.1 ml (44 mmol) of triethylamine were dissolved in 50 ml of dichloromethane. 4.2 g (22 mmol) of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride was added to the solution under cooling with ice, and they were stirred for 10 minutes and then at room temperature for one hour. Water is added to the reaction mixture to terminate the reaction. The mixture was treated with dichloromethane as the extractant in an ordinary manner to obtain the crude product, which was purified by the silica gel column chromatography (volume ratio of hexane:ethyl acetate=3:1) to obtain the title compound.
