実験手順
To an ice cooled solution of 2(S)-amino-3(R)-(4-iodophenyl)-butyric acid (124 mg, 0.42 mmol) in methanol (0.5 mL) was added dropwise thionyl chloride (150 μL, 2.0 mmol). Methanol (1 mL) was added and the reaction mixture was heated to reflux for 2 hr. After cooling, the mixture was filtered and the filtrate concentrated by rotoevaporation to yield 2(S)-amino-3(R)-(4-iodophenyl)-butyric acid, methyl ester hydrochloride (116 mg, 82% yield).
