Tert-Butylamine → 6'-[2-allyl-6-({4-[(tert-butylamino)methyl]phenyl}amino)-3-oxo-2,3-dihydro-1H-pyrazolo[3,4-d]pyrimidin-1-yl]-2H-1,2'-bipyridin-2-one

Reaktionsschritte

Chloromethanesulfonic acid (37 μL) was added to a tetrahydrofuran solution (10 mL) of 6′-[2-allyl-6-{[4-(hydroxymethyl)phenyl]amino}-3-oxo-2,3-dihydro-1H-pyrazolo[3,4-d]pyrimidin-1-yl]-2H-1,2′-bipyridin-2-one (110 mg) and triethylamine (164 μL), and stirred at room temperature for 1 hour, then tert-butylamine (500 μL) was added to the reaction liquid, and stirred for 6 hours. Chloroform and aqueous sodium hydrogencarbonate solution were added to the reaction liquid, and the organic layer was separated. The organic layer was washed with saturated saline water, then dried with anhydrous magnesium sulfate, filtered, the solvent was evaporated away, and the resulting crude product was purified through basic silica gel column chromatography (hexane-ethyl acetate/ethanol (19/1) mixture) to give the entitled compound as a white solid substance (9.2 mg).
