Procedure

To a solution of 195 mg of tert-butyl 2-((4-((6-((1-tert-butyl-1H-pyrazol-5-yl)amino)pyridin-2-yl)methyl)-1-(2-fluoro-3-(trifluoromethyl)benzoyl)piperidin-4-yl)carbonyl)hydrazinecarboxylate in 4 ml of chloroform was added 2 ml of trifluoroacetic acid at 0° C. The reaction mixture was stirred at 0° C. for 2 hours and at room temperature for 2 hours, followed by concentrating in vacuo. The resulting residue was basified with saturated aqueous sodium bicarbonate solution, and extracted with ethyl acetate. The ethyl acetate solution was dried over anhydrous magnesium sulfate, and filtered. The filtrate was concentrated in vacuo. The resulting residue was purified by a silica gel column chromatography (eluent: chloroform to chloroform/methanol=10/1) to give the title compound as a colorless oil.
