Reaction Steps

To a mixture of 4-bromo-5-methoxy-3-[1-[3-methyl-4-(morpholine-4-carbonyl)-1H-pyrrol-2-yl)-meth-(Z)-ylidene]-1,3-dihydro-indol-2-one (223 mg, 0.5 mmol) and phenylboronic acid (73 mg, 0.6 mmol) in DME/water (5 mL) were added Palladium catalyst Pd(PPh3)2Cl2 (10.5 mg) and sodium carbonate (106 mg, 1 mmol). The system was degassed and then charged with nitrogen. The degas procedure was repeated for three times. The mixture was stirred under nitrogen at 85° C. oil bath for overnight. TLC showed some de-bromination of the starting material. The degass procedure was repeated for three more times and the heating was continued for 3 more days. The mixture was cooled to room temperature, the unreacted starting material was filtered off and the mother liquor was concentrated. The residue was purified on a silica gel column to give 21 mg of 5-methoxy-3-[1-[3-methyl 4 (morpholine-4-carbonyl)-1H-pyrrol-2-yl]-meth-(Z)-ylidene]-4-phenyl-1,3-dihydro-indol-2-one.
