実験手順

C-[6-(3-Fluoro-benzenesulfonyl)-1,2,3,4-tetrahydro-naphthalen-1-yl]-methylamine hydrochloride (0.12 gms, 0.338 mmole), 1-hydroxybenzotriazole (0.07 g, 0.507 mmol) ethylcarbodiimide (0.10 g, 0.507 mmol), triethylamine (0.3 mL, 2.0 mmol) and acetic acid 2-oxo-propyl ester (0.05 g, 0.40 mmol) were dissolved in 10 mL methylene chloride. The reaction mixture was stirred at room temperature for 24 hours. The reaction was quenched with water, and the entire mixture was absorbed on to silica gel and medium pressure chromatography, and eluted with ethyl acetate//hexanes (3:1) to give 0.1 g of acetic acid {[(R)-6-(3-fluoro-benzenesulfonyl)-1,2,3,4-tetrahydro-naphthalen-1-ylmethyl]-carbamoyl}-methyl ester.
