Reaction Steps
In 30 ml of dimethylformamide were dissolved 3.82 g of 3-carboxymethylrhodanine and 3.54 g of p-diethylaminobenzaldehyde, and the solution was stirred at 100° C. for 3 hours. After termination of the reaction, the solution was poured into water, and the formed precipitate was recovered by filtration, washed with water and recrystallized from acetone to obtain 3-carboxymethyl-5-(p-diethylaminobenzylidene)rhodanine (the yield was 87%).
