Reaction Steps

To a solution of 2-(methyloxy)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzaldehyde (610 mg, 2.33 mmol) in dioxane (19 mL) and H2O (6.3 mL), was added 5-bromo-3-[1-(ethylsulfonyl)-4-piperidinyl]-1H-indole-7-carboxamide (963 mg, 2.33 mmol), and sodium carbonate (1.48 g, 13.9 mmol). After flushing with Argon for 10 min, tetrakis(triphenylphosphine)palladium(0) (134 mg, 0.166 mmol) was added. The reaction was heated in the microwave 120° C. for 120 min. Compound was purified by flash chromatography using DCM and MeOH to give 632 mg of 3-[1-(ethylsulfonyl)-4-piperidinyl]-5-[3-formyl-4-(methyloxy)phenyl]-1H-indole-7-carboxamide (58%).
