Participants

Reaction Steps

1 g of 2-(2-furyl)-4-methyl-1,3,4-thidiazolidine-5-thione was dissolved in 50 ml of warm ethanol, and after cooling to room temperature 1.26 g of dimethyl sulphate was added. After stirring for 2.5 hours at 50°, 0.69 g potassium was added, the mixture was heated for 1.5 hours at 50°, then allowed to stand overnight. The reaction mixture was filtered and the filtrate was evaporated to dryness. The residue was recrystallised from ethanol and pure S-methyl 3-furfurylidene- 2-methyl-dithiocarbazate (mp = 103°) was obtained.
