实验过程

Into a reaction flask were added 3-bromo-5-{[(2-{[3-(3-bromopropyl)phenyl]amino}-5-chloropyrimidin-4-yl)amino]methyl}phenol (2.97 g, 5.64 mmol), tetrahydrofuran (30 mL), and a solution of sodium hydroxide in water (33.8 mL, 1.0 M). The reaction mixture was stirred at rt over two days. The mixture was filtered, and then the cake was washed with water, MeOH, and EtOAc successively to provide the desired product (1.33 g, 53%) as an off-white powder.
