실험 절차

To a solution of 5-(3-(2-((tert-butyldimethylsilyl)oxy)ethyl)isoxazol-5-yl)-N2-(3-fluorophenyl)-N4-propylpyrimidine-2,4-diamine (S4, 22 mg) in tetrahydrofuran (1 mL), a 1.0 mol/L solution of tetrabutylammonium fluoride in tetrahydrofuran (69 μL) was added under ice cooling, and the mixture was stirred at room temperature for 3 hours. To the reaction mixture, saturated aqueous sodium hydrogencarbonate and ethyl acetate were added. The organic layer was separated, washed successively with water and saturated aqueous sodium chloride, and then dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (eluent, 70 to 5% hexane in ethyl acetate) to obtain 2-(5-(2-((3-fluorophenyl)amino)-4-(propylamino)pyrimidin-5-yl)isoxazol-3-yl)ethanol (S5, 5.3 mg) as white solid.
