Reaction Steps

N-{5-[5-fluoro-2-oxo-1,2-dihydro-indol-(3Z)-ylidenemethyl]-2,4-dimethyl-1H-pyrrol-3-yl}-3-bromo-propionamide (548 mg, 1.0 eq) was dissolved in 4 ml of DMF, stirred at room temperature to obtain a solution. To the solution was added 4-ethylpiperazine (850 mg, 4.0 eq). The reaction mixture was heated to 50° C. and reacted for 4 h. Once the reaction was completed as indicated by TLC, the reaction solution was added to 200 ml of ethyl acetate. Solid product was formed, collected by filtration, washed with ethyl acetate, dried, and purified by column chromatograph to obtain the target compound of 312 mg (yield 32%).
