Participants

Reaction Steps

Crude carboxymethyl 4-aminobenzenecarbodithioate (7.48 g, 0.033 mole) was dissolved in 0.5 N (66 ml) sodium hydroxide solution containing 10% by weight of sodium bicarbonate and the solution was filtered to remove traces of insoluble material. 2-Mercaptoethanol (2.9 g, 0.037 mole) was added to the stirred filtrate and the reaction mixture soon became turbid as the product began to separate out. After standing for 1 hour at room temperature, the orange precipitate was filtered off, washed with water, and dried in vacuo at a temperature of below 50°C. The yield of the product, an orange crystalline powder, m.p. 87.5°-89.5° was 6.13 g or 87%.
