Abstract

phenylalanine and methylisocyanate according to the method of Dudley and B id 4 in an overall yield of 50%. The intermediate L-2-benzyl-5-methylhydantoin acid that precipitated at pH 2 was isolated and cyclized to optically active L-5-benzyl-3-methylhydantoin by refluxing in 0.5 N HC1 for 30 min. The white crystals were washed with cold water and dried in vacuo: mp 166-167
