Procedure
A mixture, under an inert atmosphere, of 5 g of cysteamine and 7.2 cm3 of ε-caprolactone is stirred for 6 hours at ambient temperature. It is then left to stand overnight, after which the mixture is heated for 4 hours at a temperature of about 60° C. At the end of this time all the ε-caprolactone is transformed. The mixture is then poured into 100 cm3 of water to which 10 g of acid resin, "Dowex 50" are added and then 3 g of powdered zinc. The whole is stirred for 4 hours at ambient temperature. The water is then removed under reduced pressure and there are obtained 10 g of 6-hydroxy N-(2-mercaptoethyl) caproamide in the form of a viscous liquid at ambient temperature whose NMR1H spectrum and thiol dosages and residual amine correspond to the expected structure.
