Reaction Steps

To a solution of methyl 6-chloro-5-(5,5-dimethyl-1,3,2-dioxaborinan-2-yl)-1H-indole-3-carboxylate (440 mg, 1.37 mmol) and 4-(4-bromophenyl)tetrahydro-2H-pyran (300 mg, 1.24 mmol) in toluene (6 mL), ethanol (3 mL), and tetrahydrofuran (3 mL) followed by the addition of 2M potassium carbonate aqueous (3 mL, 6 mmol). Nitrogen was bubbled through the reaction for 5 minutes then [1,1′-bis(diphenylphosphino)ferrocene]dichloro palladium-dichloromethane complex (120 mg, 0.143 mmol) was added and the reaction heated to 115° C. for 16 hours. The reaction was then cooled to room temperature and filtered through a pad of celite washing with ethyl acetate. The filtrate was concentrated under reduced pressure. The crude product was purified using the Biotage Isolera One (SNAP 50 g silica gel column) and eluting with a gradient of 0-100% ethyl acetate/heptane yielding 360 mg of the title compound as a solid.
