Reaction Steps
To a suspension of 2.5 g of glyoxal-sodium bisulfite in 10 ml of water was added dropwise 0.5 g of ethylenediamine with ice-cooling and the mixture was stired for additional 1 hour. To this solution was added dropwise with ice-cooling the dithiolate aqueous solution which had been prepared previously by the reaction of 1.5 g of diisopropyl malonate with 0.8 g of carbon disulfide in the presence of 3.3 g of 30% aqueous potassium hydroxide.
