Procedure

0.62 Gram of monoethanolamine was added to a mixture of 1.2 g (0.005 mole) of 3-carboxymethyl-5ethoxymethylidenerhodanine and 10 ml of ethanol. The reaction was carried out at a temperature of 50° to 60° C. for 1 hour. The formed precipitate was separated by filtration and recrystallized from a mixture of methanol and ether (7/3 by volume) to give 0.85 g of 3-carboxymethyl-5-hydroxyethylaminomethylidenerhodanine ethanolamine salt in the form of light brown crystal (yield: 53.1 %).
