Reaction Steps

To a solution of 4-(4-bromo-phenyl)-1,3-dihydro-indol-2-one (72 mg, 0.25 mmol) and 4-[(cis)-3,5-dimethyl-piperazine-1-carbonyl)-3,5-dimethyl-1H-pyrrole-2-carbaldehyde (68.5 mg, 0.25 mmol) in ethanol (2 mL) was added piperidine (3 drops). The reaction mixture was stirred at room temperature for three days. A yellow solid product was precipitated out, filtered, washed by ethanol for three times, and dried under high vacuum to provide pure product 4-(4-bromo-phenyl)-3-[4-[(cis)-3,5-dimethyl-piperazine-1-carbonyl)-3,5-dimethyl-1H-pyrrol-2-ylmethylene]-1,3-dihydro-indol-2-one as a yellow solid (38 mg, 28%).
