Procedure

To a solution of 2-(5-(2-((3-fluorophenyl)amino)-4-(propylamino)pyrimidin-5-yl)isoxazol-3-yl)ethanol (S5, 5.3 mg), phthalimide (10.9 mg) and triphenylphosphine (19.4 mg) in tetrahydrofuran (1 mL), a 1.9 mol/L solution of diisopropyl azodicarboxylate in toluene (39 μL) was added under ice cooling, and the mixture was stirred at the same temperature for 35 minutes, and then stirred at room temperature for 2 hours and 30 minutes. The solvent was evaporated under reduced pressure, and the obtained residue was purified by silica gel column chromatography (eluent, 84 to 35% hexane in ethyl acetate) to obtain 2-(2-(5-(2-((3-fluorophenyl)amino)-4-(propylamino)pyrimidin-5-yl)isoxazol-3-yl)ethyl)isoindoline-1,3-dione (S6, 8.9 mg) as white solid.
