First, 4.0 g of 5,5-dimethylhydantoin was mixed with 4.0 g of sodium hydroxide and 4.0 g of water, and the mixture was stirred at 85° C. to 90° C. for 3.5 hours. The HPLC analysis (column: COSMOSIL 5C18-ARII (produced by Nacalai Tesque Inc.), mobile phase: acetonitrile/10 mM aqueous potassium dihydrogen phosphate solution=20/80, flow rate: 0.5 ml/min, detection wavelength: 210 nm, column temperature: 40° C.) of the reaction mixture showed the production of 3.38 g (yield 74.1%) of the title compound.
