Reaction Steps
A mixture, stirred under an inert atmosphere, of 5 g of cysteamine and 6.05 cm3 of δ-valerolactone is brought to a temperature of about 60°-70° C. for 15 hours. The disappearance of the δ-valerolactone is followed by VPC. The reaction mixture is then poured into 100 cm3 of water and 10 g of acid resin, "Dowex 50" and 3 g of zinc powder are added. The resulting mixture is stirred for 4 hours at ambient temperature and then left overnight. The next day the mixture is filtered and the water is evaporated under reduced pressure.
