Reaction Steps
22.7 g of 2-mercaptoethylamine hydrochloride (0.2 mol) and 32.4 g of triethylamine (0.32 mol) were introduced in suspension in 130 ml of dichloromethane at 0° C.-5° C. Over the course of 30 minutes, 12.1 g of pivaloyl chloride (0.1 mol) were added dropwise. The batch was stirred at 0° C. to 5° C. for 1 hour, at 40° C. for 1.5 hours, and then at room temperature for 12 hours. 70 ml of saturated ammonium chloride solution were added and a phase separation was carried out. This was repeated twice and the organic phases were combined, dried over sodium sulfate, and freed of their solvent under reduced pressure.
