실험 절차
A reaction mixture of 133.0 mg of oxindole, 151.2 mg of the 4-methylthiophene-2-carboxaldehyde, and 3 drops of piperidine in 3 mL of ethanol was stirred at 90° C. for 3 h. After cooling, the precipitate was filtered, washed with cold ethanol, and dried to yield 147.3 mg (61%) of the title compound as a yellow solid.
