Versuchsvorschrift
A mixture of 1.74 g. of 5-(β-methylthioethyl)hydantoin, 68 mg. of imidazole and 20 ml. of water was heated to 160° C. in a 50 ml. autoclave, and was allowed to react at 160° C. for 6 hours. After the reaction was over, the autoclave was rapidly cooled. The reaction mixture was treated by the same after-treatment as in Example 1 and methionine was obtained in yield of 80%.
