To a stirred hot solution of 2.10 g. (11.65 mM) of 6-methoxyphthalaldehydic acid and 1.57 g. (11.75 mM) of rhodanine in 8 ml. of acetic acid is added 3.12 g. (38.1 mM) of sodium acetate. The resulting solution is refluxed 0.5 hour and then poured into ice water to give a tan precipitate. The solid is collected and partially air-dried to give 5-(2-carboxy-3-methoxybenzylidene)rhodanine as a tan solid.
