To a solution of 3-[1-(ethylsulfonyl)-4-piperidinyl]-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-indole-7-carboxamide (46 mg, 0.1 mmol) in dioxane (2.0 mL, 0.7 mL) was added 3-bromo-5-formylbenzonitrile (68 mg, 0.3 mmol) and K2CO3 (83 mg, 0.6 mmol) in a microwave tube. The reaction mixture was degassed for 5 min before addition of tetrakis(triphenylphosphosphine) palladium (0) (11 mg, 0.01 mmol). The reaction was heated in a microwave for 20 min at 160° C. It was then purified by Gilson Preparatory HPLC to give 5-(3-cyano-5-formylphenyl)-3-[1-(ethylsulfonyl)-4-piperidinyl]-1H-indole-7-carboxamide.
