実験手順

1.8 g (5.2 mmol) of benzyl (3R)-3-amino-4-(3-cyanophenoxy)butyrate hydrochloride (the compound in step 2 in Example 52), 703 mg (5.2 mmol) of 1-hydroxybenzotriazole (hydrate), 997 mg (5.2 mmol) of 1-(3-dimethylaminopropyl)-3-ethyl carbodiimide hydrochloride, 526 mg (5.2 mmol) of triethylamine, and 1.14 g (5.2 mmol) of 4-(1-pyrrolidyl carbonyl)benzoic acid were stirred in dichloromethane overnight. The reaction solution was washed with 1 N hydrochloric acid, 1 N aqueous sodium hydroxide and saturated saline and dried over sulfate magnesium anhydride, and the solvent was distilled off. The resulting residue was purified by silica gel chromatography (ethyl acetate) to obtain the title compound.
