Procedure
9.7 ml of trifluoromethanesulfonic anhydride was added to a mixture of 12.9 g of 2-(((tert-butyl(dimethyl)silyl)oxy)methyl)-6-((1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazol-3-yl)amino)pyridin-4-ol, 14.2 g of 4-(dimethylamino)pyridine and 290 ml of chloroform at 0° C. The resulting mixture was stirred for 2 hours at room temperature and then diluted with ethyl acetate. The resulting solution was charged with 100 ml of 0.1 mol/l hydrochloric acid at 0° C. The organic layer separated was washed with saturated sodium bicarbonate, water and brine. The resulting organic layer was dried over magnesium sulfate and filtered, and the filtrate was concentrated under a reduced pressure. The resulting residue was purified by a silica gel column chromatography (eluent: hexane/ethyl acetate=10/1 to 1/1) to give the title compound.
