Procedure

A solution of 183 mg (1.5 mmol) of N,N-dimethylaminopyridine and 3.50 g (15 mmol) of 1-aminocyclohexanecarboxylic acid phenylmethyl ester in toluene was added to a solution of 3.27 g (15 mmol) of di-t-butyl dicarbonate in 60 ml of toluene, and the mixture was stirred at room temperature for 30 minutes. Thereafter, 3.04 g (30 mmol) of triethylamine, 1.83 g (15 mmol) of N,N-dimethylaminopyridine and 1.56 g (15.8 mmol) of 2-piperidone were added thereto, and the mixture was refluxed under heating overnight. Ethyl acetate was added to the reaction solution 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. The solvent was distilled off under reduced pressure and the obtained residue was purified by silica gel chromatography to give 4.10 g (76%) of the title compound.
