실험 절차
A 1,4-dioxane (2.2 ml) solution of the 2,5-dichloro-4-[(4-chlorophenylthio)-(2,5-difluorophenyl)methyl]pyridine (300 mg, 0.48 mmol) obtained in Example 54 and t-butyl 4-aminopiperidine-1-carboxylate (600 mg) was stirred at 120° C. for 5 days under an argon atmosphere. After cooling to room temperature, the reaction mixture was concentrated under reduced pressure. The residue thus obtained was purified by silica gel chromatography (hexane:ethyl acetate=3:1) to give the title compound (36 mg, 9%) as an oil.
