Reaction Steps

To a solution of 4-(2-fluoro-phenyl)-1,3-dihydro-indol-2-one (56.8 mg, 025 mmol) and 3-[(cis)-3,5-dimethyl-piperazine-1 carbonyl]-5-methyl-1H-pyrrole-2-carbaldehyde (62.3 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-{3-((cis)-3,5-dimethyl-piperazine-1-carbonyl]-5-methyl-1H-pyrrol-2-ylmethylene}-4-(2-fluoro-phenyl)-1,3-dihydro-indol-2-one as a yellow solid (103.5 mg, 90%).
