Reaction Steps

To 5-bromo-3-[1-(ethylsulfonyl)-4-piperidinyl]-1H-indole-7-carboxamide (20 mg, 0.048 mmol) was added 4-methyl-1-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]-2-piperazinone (31 mg, 0.097 mmol) in dioxane (3.0 mL) and H2O (1.0 mL), potassium carbonate (13 mg, 0.097 mmol) and chloro(di-2-norbornylphosphino)(2-dimethylaminomethylferrocen-1-yl)palladium (II) (10 mg, 0.016 mmol). The reaction mixture was reacted in a microwave at 160° C. for 10 min. The reaction mixture was heated in a microwave at 160° C. for 10 min. The reaction mixture was concentrated under Nitrogen and purified by Gilson Preparatory HPLC. The desired fraction in CH3CN and H2O was treated with saturated potassium carbonate to neutralize salts and then concentrated to give 1.9 mg the title compound (8%).
