The 1-(4-nitrophenyl)piperidine-4-carboxylic acid (10.1 g, 40 mmol) obtained in Example 3(1) was dissolved in N,N-dimethylformamide (25 ml), and morpholine (5.2 g, 60 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (9.2 g, 48 mmol), and 1-hydroxybenzotriazole monohydrate (6.7 g, 44 mmol) were added thereto, followed by stirring overnight under heat at 70° C. After cooling to room temperature, water was added thereto, and the precipitate was collected by filtration and dried under heat under reduced pressure, thereby obtaining 1-(4-nitrophenyl)piperidine-4-morpholinecarboxamide (12.1 g, 95%) as a yellow solid.
