Procedure

To a solution of 4-(4-trifluoromethoxy-phenyl)-1,3-dihydro-indol-2-one (73.3 mg, 0.25 mmol) and 5-formyl-2,4-dimethyl-1H-pyrrole-3-carboxylic acid (2-[1,2,3]triazol-1-yl-ethyl)amide (67.9 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 2,4-dimethyl-5-[2-oxo-4-(4-trifluoromethoxy-phenyl)-1,2-dihydro-indol-3-ylidenemethyl]-1H-pyrrole-3-carboxylic acid (2-[1,2,3]triazol-1-ylethyl)amide as a yellow solid (49.6 mg, 37%).
