実験手順

A 100 mL round-bottomed flask was charged with 1-(1-(4-methoxybenzyl)-4-(4-amino-2-fluorophenoxy)-1H-pyrazolo[3,4-b]pyridin-3-yl)-N,N-dimethylpiperidin-4-amine (35.8 mg, 0.07298 mmol), 2-(4-fluorophenyl)-3-oxo-2,3-dihydropyridazine-4-carboxylic acid (25.63 mg, 0.1095 mmol), N1-((ethylimino)methylene)-N3,N3-dimethylpropane-1,3-diamine hydrochloride (69.95 mg, 0.3649 mmol), 1H-benzo[d][1,2,3]triazol-1-ol (49.30 mg, 0.3649 mmol), N-ethyl-N-isopropylpropan-2-amine (47.16 mg, 0.3649 mmol) and DMF (5 mL). The reaction mixture was stirred at room temperature overnight. Then the reaction was partitioned between EtOAc and H2O. The phases were separated and the aqueous phase was re-extracted with EtOAc. The combined organic layers were dried (Na2SO4), filtered and concentrated to yield a crude product. The crude product was purified by silica gel chromatography (DCM/7 M NH3 in MeOH from 100/1 to 10/1, v/v) to afford product (33.1 mg, 64.18%). LRMS (APCI pos): m/e 707 (M+1).
