実験手順
A mixture of 955 mg of 3-carboxymethylrhodanine, 516 mg of sodium acetate, 10 ml of acetic acid and 637 mg of benzaldehyde was heat-refluxed for 2 hours. To the reaction mixture was added 20 ml of water, and the precipitated crystals were filtered. The resulting crystals were recrystallized from ethanol to obtain 699 mg of the titled compound.
