Versuchsvorschrift

5-(o-Hydroxybenzylidene)-hydantoin was prepared in the same manner as in Example 4, except that 22.2 g (0.25 mol) of β-alanine and 61.1 g (0.50 mol) of o-hydroxybenzaldehyde were used in lieu of glycine and p-hydroxybenzaldehyde, respectively, and that the reaction time was 6 hours. During the reaction, the pH of the reaction mixture was 9.6 to 9.2.
