실험 절차

3-chloro-5-[(5-chloro-1H-1,2,3-benzotriazol-4-yl)oxy]benzonitrile (140 mg, 0.459 mmol) and lithium tert-butoxide (37 mg, 0.459 mmol) were dissolved in DMF (1 mL) under N2 and allowed to stir for 20 minutes. After this time, the reaction was cooled to 0° C. and 3-(chloromethyl)-N,1-bis(4-methoxybenzyl)-1H-pyrazolo[3,4-b]pyridin-6-amine as a solution in DMF (1 mL) was added dropwise. After 1 hour, the reaction was quenched with saturated aqueous ammonium chloride (3 mL), diluted with water (3 mL) and the mixture was extracted with ethyl acetate (2×25 mL). The combined organic fractions were washed with dilute brine (4×10 mL), dried (MgSO4), filtered and the solvent was evaporated under reduced pressure. The resulting residue was purified by automated column chromatography on silica gel (12 g), eluting with 0-100% EtOAc/hexanes to give the title compound. LRMS (M+1)=690.5.
