実験手順
To a stirred hot solution of 4.23 g. (23.5 mM) of 4-methoxyphthalaldehydic acid and 3.13 g. (23.5 mM) of rhodanine in 16.5 ml. of acetic acid is added 6.33 g. (77.2 mM) of anhydrous sodium acetate. The resulting hot solution is refluxed for 0.5 hour, whereupon a solid yellow mass forms. The mixture is cooled, poured into water, to yield 5-(2-carboxy-5-methoxybenzylidene)rhodanine.
