A toluene (5 mL) suspension of (4aS,8aS)-2,2-dimethyldecahydroquinoxaline (200 mg, 1.19 mmol), 4-bromo-1-(triisopropylsilyl)-1H-pyrrolo[2,3-b]pyridine (462 mg, 1.31 mmol), Pd(OAc)2 (13.3 mg, 0.0594 mmol), tBu3P.HBF4 (17.2 mg, 0.0594 mmol), and t-BuONa (137 mg, 1.43 mmol) was stirred at 100° C. for 4 hours in a nitrogen atmosphere. Insoluble matter was filtered through celite, and the filtrate was concentrated. The obtained residue was purified by basic silica gel column chromatography (AcOEt/hexane) to obtain (4aS,8aS)-3,3-dimethyl-1-(1-(triisopropylsilyl)-1H-pyrrolo[2,3-b]pyridin-4-yl)decahydroquinoxaline (439 mg, 84%) in a white amorphous solid form.
