Procedure

A dioxane (1.5 ml) solution of the 2,5-dichloro-4-[(4-chlorophenylthio)(2,5-difluorophenyl)methyl]pyridine (191 mg, 0.458 mmol) obtained in Example 54 and 3-amino-2,2-dimethylpropan-1-ol (515 mg, 5.00 mmol) was heated at 120° C. for 3 days in a sealed tube. The reaction mixture was cooled to room temperature and then, concentrated under reduced pressure. Ethyl acetate was added to the residue. The resulting mixture was washed sequentially with water and brine, dried over anhydrous sodium sulfate, and filtered. The filtrate was concentrated under reduced pressure. The residue thus obtained was subjected to silica gel column chromatography. The fraction obtained from the hexane:ethyl acetate=3:1 eluate was concentrated under reduced pressure to give the title compound (199 mg, 0.412 mmol, 90%) as an amorphous substance.
