Potassium Carbonate → HCID 54053038, compound

Participants

Reaction Steps

To liberate the base, 52.4 g (0.222 Mol) of 3-(1-methylallyl)-5-methyl-2,4-thiazolidinedione-2-hydrazone hydrochloride is dissolved in 150 ml of water, and the solution saturated, with ice cooling and stirring, with potassium carbonate. The oil which precipitates is taken up in a mixture of 100 ml of methylene chloride and 100 ml of petroleum ether (B.P. 40°-60°), separated from the aqueous phase, and extracted by shaking with a solution of 25 g of potassium carbonate in 75 ml of water. The organic phase is separated, and concentrated in a water-jet vacuum to obtain 3-(1-methylallyl)-5-methyl-2,4-thiazolidinedione-2-hydrazone in the form of a colourless oil.
