Reaction Steps
To a hot stirred solution of 0.90 g. (5.0 mM) of 5-methoxyphthalaldehydic acid and 0.67 g. (5.0 mM) of rhodanine in 4 ml. of acetic acid is added 1.35 g. (16.4 mM) of anhydrous sodium acetate. After refluxing 0.5 hour, the solid yellow mass is cooled, poured into water, and filtered to separate 5-(2-carboxy-4-methoxybenzylidene)rhodanine as a yellow solid.
