Reaction Steps
Under a nitrogen atmosphere, 22.7 g of 2-mercaptoethylamine hydrochloride (0.2 mol) and 44.3 g of potassium carbonate (0.32 mol) were introduced at room temperature in solution in 130 ml of water. The solution was warmed to 40° C. and 12.0 g of valeryl chloride (0.1 mol) were added dropwise over the course of 15 minutes. The batch was stirred at 40° C. for 3 hours and then cooled to room temperature. 70 ml of dichloromethane were added and a phase separation was carried out. The organic phase was washed with 50 ml of 20% strength ammonium chloride solution, dried over sodium sulfate and freed of its solvent under reduced pressure.
