Procedure

To a solution of 4-phenyl-1,3-dihydro-indol-2-one (52.3 mg, 0.25 mmol) and 4-[(cis)3,5-dimethyl-piperazine-carbonyl]-3-methyl-1H-pyrrole-2-carbaldehyde (64.8 mg, 0.26 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 3-[4-((cis)-3,5-dimethyl-piperazine-1-carbonyl]-3-methyl-1H-pyrrol-2-ylmethylene]-phenyl-1,3-dihydro-indol-2-one as a yellow solid (21.5 mg, 20%).
