実験手順

1-(4-Methoxybenzyl)-N-(2-morpholinoethyl)-1H-pyrazolo[3,4-b]pyridin-4-amine (0.025 g, 0.06804 mmol) was charged to a pressure tube in DMF (1 mL). NaH (0.004082 g, 0.1021 mmol) was added, and the reaction was allowed to stir at room temperature for 15 minutes. 1,2-difluoro-4-nitrobenzene (0.009389 ml, 0.08505 mmol) was added, and the reaction was stirred at room temperature for 3 hours. The reaction mixture was diluted with EtOAc (25 mL) and washed with water (15 mL). The organics were then dried with brine, dried over Na2SO4, filtered and concentrated.
