実験手順

In a 25 mL round-bottomed flask, 6-(2-(dimethylamino)ethylamino)-1H-pyrrolo[2,3-b]pyridine-3-carbonitrile (211 mg, 920 μmol), 6-tert-butyl-8-fluoro-2-(1-hydroxy-1,3-dihydrobenzo[c][1,2]oxaborol-4-yl)phthalazin-1(2H)-one (324 mg, 920 μmol, Eq: 1.00) and copper acetate (226 mg) were combined with 1,2-Dichloroethane (6.73 ml) to give a blue suspension. Pyridine (146 mg, 149 μl, 1.84 mmol, Eq: 2) was added. The reaction mixture was heated to 45° C. and stirred for 2 d. Mixture was poured into 20 mL sat NH4Cl and extracted with EtOAc (3×20 mL). The organic layers were dried over MgSO4 and concentrated in vacuo. The crude material was purified by flash chromatography (silica gel, 40 g, 5% to 10% MeOH in DCM), then by HPLC to give 1-(3-(6-tert-butyl-8-fluoro-1-oxophthalazin-2(1H)-yl)-2-(hydroxymethyl)phenyl)-6-(2-(dimethylamino)ethylamino)-1H-pyrrolo[2,3-b]pyridine-3-carbonitrile (18 mg, 3.5%)
