Participants

Reaction Steps

To a stirred hot solution of 0.45 g. (2.50 mM) of 3-methoxyphthalaldehydic acid and 0.34 g. (2.50 mM) rhodanine in 3 ml. of acetic acid is added 0.68 g. (8.2 mM) of anhydrous sodium acetate. The resulting solution is refluxed 1.5 hours, cooled, and poured into 40 ml. of water to give a yellow gum which slowly solidifies to a yellow solid. The solid is collected, washed with water, and air-dried to give 5-(2-carboxy-6-methoxybenzylidene)rhodanine.
