Into a suitable reaction vessel containing 5 ml of pyridine, there is added one g (0.035 mols) of 3-hydroxymethyl-diphenylhydantoin, 0.36 g (0.0035 mols) of N,N-dimethylglycine and 0.79 g (0.0035 mols) of dicyclohexylcarbodiimide (DCCI). The reaction mixture is stirred at room temperature for a period of approximately 24 hours, after which the final product, mp 128°-130°, yield 0.86 g (66.7%) is obtained.
