Reaction Steps

First, 5.0 g of 5-benzylthiomethyl-5-methylhydantoin was mixed with 3.6 g of potassium hydroxide and 3 g of water, and the mixture was subjected to reaction at 94° C. to 96° C. for 12 hours. The HPLC analysis (column: COSMOSIL 5C18-ARII (produced by Nacalai Tesque Inc.), mobile phase: acetonitrile/10 mM aqueous potassium dihydrogen phosphate solution=30/70, flow rate: 1.0 ml/min, detection wavelength: 254 nm, column temperature: 40° C.) of the reaction mixture showed the production of 3.56 g yield 66.4%) of the title compound.
