Potassium Iodide → Ethyl 2-(p-chlorobenzylthio)-propionate

Participants

Reaction Steps

A mixture of 19.5 ml (0.15 mol) of 4-chlorobenzylmercaptan, 27.1 g (0.15 mol) of ethyl α-bromopropionate, 21 g of potassium carbonate and 0.1 g of potassium iodide in 100 ml of anhydrous acetone is maintained under reflux for 6 hours. The mixture is filtered, the precipitate is washed with acetone and the filtrate is evaporated in vacuo. 200 ml of ether are added to the residue and the ether solution is washed with dilute NaOH, dilute HCl and water.
