Procedure

IPEA (0.555 mL), HOBt (175 mg) and EDC (249 mg) were added to a solution of 5-chloro-2-(4-dimethylaminophenyl)pentanoic acid (317 mg) and tert-butyl carbazate (103 mg) in DMF (2.5 mL), and the reaction solution was stirred at room temperature for five hours. Ethyl acetate and water were added to the reaction solution, and the organic layer was separated. The resulting organic layer was washed with brine, dried over anhydrous magnesium sulfate and then concentrated under reduced pressure. The residue was purified by silica gel column chromatography (elution solvent: heptane+ethyl acetate) to obtain 106.9 mg of the title compound. The property values of the compound are as follows.
