実験手順

450 mg (2.5 mmol) of 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride was added to a solution of 910 mg (2.1 mmol) of 1-[[[4-[2-(4-methyl-1-piperazinyl)-4-thiazolyl]phenyl]carbonyl]amino]cyclohexanecarboxylic acid in 20 ml of dimethylformamide. After the mixture was stirred at room temperature for 4 hours, the reaction solution was concentrated under reduced pressure, ethyl acetate was added thereto, and the mixture was successively washed with water, a saturated aqueous sodium hydrogencarbonate solution and saturated brine, followed by drying with anhydrous sodium sulfate. The solvent was distilled off under reduced pressure to obtain 577 mg (67%) of the title compound.
