Triethanolamine → HCID 178484944, compound

Participants

Reaction Steps

A mixture of 0.68 g (0.010 mole) of methylamine hydrochloride and 5 ml of ethanol, which was neutralized with 1.0 g (0.010 mole) of triethanolamine, was added to a mixture of 1.2 g (0.005 mole) of 3-carboxymethyl-5ethoxymethylidenerhodanine and 10 ml of ethanol. The reaction was conducted at a temperature of 50° to 60° C. for 1 hour. The reaction mixture was concentrated and the resulting residue was recrystallized from ethanol to give 1.0 g of 3-carboxymethyl-5-methylaminomethylidenerhodanine methylamine salt (yield: 79.2 %).
