참여 물질

반응 단계

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) and H2O (0.7 mL) was added 3-bromo-5-formylbenzonitrile (68 mg, 0.3 mmol), and potassium carbonate (83 mg, 0.6 mmol). The mixture was degassed for 5 min before addition of tetrakis(triphenylphosphine) palladium (0) (12 mg, 0.01 mmol). The mixture was reacted in the microwave at 160° C. for 20 min. The compound was purified by Gilson Preparatory HPLC to give 5-(3-cyano-5-formylphenyl)-3-[1-(ethylsulfonyl)-4-piperidinyl]-1H-indole-7-carboxamide.
