After neutralizing 203 g (500 mmol) of phenylmethyl 1-aminocyclohexanecarboxylate•p-toluenesulfonate with a 10% sodium carbonate solution, the mixture was extracted with chloroform and dried over anhydrous magnesium sulfate. The solid material was filtered off, and after adding 56 g (550 mmol) of triethylamine to the chloroform layer, 75 g (500 mmol) of 4-morpholinecarbonyl chloride was added dropwise, and the mixture was heated in an oil bath (60° C.) for 3 days. After completion of the reaction, the reaction mixture was washed successively in the order of water, a 10% aqueous potassium hydrogen sulfate solution, a saturated aqueous sodium hydrogen carbonate solution and a saturated NaCl solution, and dried over anhydrous sodium sulfate. After removing the solvent under reduced pressure, the resulting crystals were washed with ether to obtain 151 g (Yield: 87%) of the title compound.
