実験手順

Add triethylamine (8.1 g, 79.9 mmol) dropwise to a solution of 2-amino-1-(2-methoxyphenyl)ethanone hydrochloride (13.6 g, 67.4 mmol) and octanedioic acid monomethyl ester (14.0 g, 74.2 mmol) in methylene chloride (600 mL) at 0° C. under nitrogen, and then add EDC HCl (15.5 g, 81.0 mmol). Stir the mixture for 4 hours and warm to room temperature with stirring for an additional 18 hours. Dilute the mixture in ethyl acetate (1.2 L), wash sequentially with water (300 mL), 1 N HCl (300 mL), brine (300 mL), saturated sodium, bicarbonate solution (300 mL) and brine (300 mL), and dry over sodium sulfate. Remove the solvent under reduced pressure to afford 7-[2-(2-methoxyphenyl)-2-oxoethylcarbamoyl]heptanoic acid methyl ester (20.0 g, 88%), which is used in the next step without further purification.
