To a solution of 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)indolin-2-one (195 mg, 0.75 mmol) in EtOH (3 ml) was added N-(2-(diethylamino)ethyl)-5-formyl-2,4-dimethyl-1H-pyrrole-3-carboxamide (200 mg, 0.76 mmol) and piperidine (82 μL, 0.83 mmol). The mixture was stirred at 80° C. for 1 hour. After cooled down to room temperature, the reaction mixture was concentrated, filtrated, and washed with EtOH to give (Z)—N-(2-(diethylamino)ethyl)-2,4-dimethyl-5-((2-oxo-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)indolin-3-ylidene)methyl)-1H-pyrrole-3-carboxamide (218 mg) as yellow solid.
