Reaction Steps

After 1.33 g of 60% sodium hydride was introduced to 15 ml of tetrahydrofuran and cooled to 5° C., 5.84 g of 1,1,1,3,3,3-hexafluoro-2-propanol was added dropwise. The mixture was stirred at 5° C. for 30 minutes, and then 3.0 g of 2-chloro-4-methyl-5-nitropyridine dissolved in 10 ml of tetrahydrofuran was added dropwise, this being stirred at room temperature for 3 hours. After being left at room temperature for 3 days, ethyl acetate and water were added thereto, and the organic layer was separated and washed with saturated brine. The organic layer was dried over anhydrous magnesium sulfate, and the solvent was distilled off under reduced pressure. Thus obtained residue was purified by silica gel column chromatography (eluent:hexane:ethyl acetate=10:1) to give 4.5 g (yield 80%) of the title compound as a yellow oil.
