Reaction Steps

To a solution of 5-bromo-3-(1H-indol-5-yl)-1-tosyl-1H-pyrrolo[2,3-b]pyridine [Intermediate B] (0.20 g, 0.43 mmole) in CH3CN (4 mL) in a Personal Chemistry microwave reaction vial was added 4-formylphenylboronic acid (64 mg, 0.43 mmol), bis(triphenylphosphine)-palladium(II) dichloride (40 mg, 0.057 mmol), and 1 M Na2CO3 (2 mL). The resulting mixture was de-gassed with Ar for 10 min, after which it was heated at 150° C. for 10 min in a Personal Chemistry Optimizer. The organic layer was separated, filtered, and partitioned between EtOAc and brine. The organic layer was dried over MgSO4, filtered, and concentrated in vacuo to give Intermediate AJ. HPLC retention time: 3.01 minutes. MS ESI (m/z): 492.4 (M+H)+, calc. 491.
