Reaction Steps

To a solution of 3-iodo-1H-pyrazolo[3,4-d]pyrimidin-4-amine (1) (5.22 g, 20 mmol) in DMF (60 mL) were added K2CO3 (8.3 g, 60 mmol) and 1-fluoro-4-nitrobenzene (2.96 g, 21 mmol). After the resulting mixture was stirred at 100° C. for 24 hr under N2 atmosphere, the reaction mixture was cooled to RT before pouring into water (200 mL). The precipitate was collected, washed with water and dried to provide 3-iodo-1-(4-nitrophenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (27) (6.8 g, 89%) as light yellow solid. LC-MS (ESI): m/z (M+1)383.1.
