実験手順

A solution of 114 mg (0.9 mmol) of N,N-dimethylaminopyridine and 2.17 g (9.3 mmol) of 1-aminocyclohexanecarboxylic acid phenylmethyl ester in methylene chloride was added to a solution of 2.03 g (9.3 mmol) of di-t-butyl dicarbonate in 60 ml of methylene chloride, and the mixture was stirred at room temperature for 30 minutes. Thereafter, a solution of 1.88 g (18.6 mmol) of triethylamine and 1.86 g (9.8 mmol) of 1-(benzoyl)piperazine in methylene chloride was added, and the mixture was stirred at room temperature overnight. After the reaction solution was concentrated, the residue was dissolved in ethyl acetate, and the mixture was successively washed with water, a 10% aqueous potassium hydrogensulfate solution, a saturated aqueous sodium hydrogencarbonate solution and saturated brine, followed by drying with anhydrous sodium sulfate. After the solvent was distilled off under reduced pressure, the obtained crystal was washed with diethyl ether to obtain 3.60 g (86%) of the title compound.
